Synthesis and Photochemical Properties of Cyclometalated Styryl-substituted 2-Phenylpyridinato Platinum (II) Complexes
No full text本論文之目的為合成一系列 [(C^N)Pt(O^O)] 及其分子模型計算並探討其光化學性質。C^N 為含有對胺基苯乙烯取代之苯吡啶 (PhDM, PhDP, PyDM, PyDP)期為單陰離子之配位基，而O^O為乙醯丙酮配位基。們利用X-ray繞射鑑定化合物PhDP與PtPhDP之晶體結構。DFT與TDDFT理論計算錯合物及其配位基之分子模型與激發態能階，並利用UV-Vis 吸收光譜、放射光譜及反式→順式光致異構化量子產率探討錯合物及其配位基之光化學性質。所有PtII錯合物含有配位基內電荷轉移 (ILCT) 之單重態激發態且錯合物PtPhDM 及PtPhDP相較於錯合物PtPyDM及PtPyDP含有較強的鄰位ILCT性質。有錯合物之磷光光譜是在低溫77 K測得，室溫下之磷光量子產率則非常低 (<10-3)。此外，激發態行為主要是由二苯乙烯或是含氮二苯乙烯部分所主導。激發態去活化路徑是由反式→順式異構化所主導，而跟取代基的位置與種類無關。最低三重激發態為配位基內電荷轉移 (3ILCT) 態。錯合物PtPyDM及PtPyDP之3ILCT激發態之分布主要是區域化在含氮二苯乙烯部分，而錯合物PtPhDM及PtPhDP之3ILCT激發態則是由胺基二苯乙烯至吡啶陽離子非定域分布。以上現象可知，對胺基苯乙烯取代之鉑錯合物其激發態主要是區域化在二苯乙烯及含氮二苯乙烯部分，且可由對位及鄰位共軛效應來解釋其光物理性質。The synthesis, molecular modeling, and photochemical properties of four Pt(II) complexes [(C^N)Pt(O^O)] are reported. C^N is a monoanionic cyclometalating styrene-incorporated phenylpyridine ligand (PyDM, PyDP, PhDM, and PhDP) and O^O is an acetylacetone (acac) ligand. The solid-state structures of PhDP and PtPhDP were characterized by X-ray diffraction. Molecular modeling was carried out with DFT and TD-DFT methods, and photochemical properties were investigated with UV-Vis absorption, steady-state luminescence, and the measurements of trans→cis photoisomerization quantum yield. The lowest singlet excited-state (S1) for all the Pt complexes is of ILCT character and it is more meta-ph ILCT character for PtPhDM and PtPhDP than for PtPyDM and PtPyDP. All PtII complexes show phosphorescence only at 77 K but not at room temperature. The major triplet deactivated pathway is the nonradiative trans→cis isomerization. Furthermore, the excited-state behavior which is independent of the substitution position mainly dictated by the stilbene and azastilbene moiety. The lowest excited state (T1) is an intraligand charge transfer state (3ILCT). The 3ILCT state is localized on the azastilbene moiety for PyDM and PyDP systems but is from aminostilbene to the pyridinium moiety for PhDM and PhDP systems. As a result, the behavior of these systems can be understood by a para vs meta conjugation effect.Table of Contents誌 II文摘要 IIIbstract IVable of Contents Vist of Figures VIIIist of Tables XVist of Schemes XVIIIefinition XIXhapter 1 Introduction 1.1 Photochemistry 1.2 Photochemistry of Stilbene and Stilbene Derivatives 4.3 Photochemistry of Platinum Complexes 19.4 Objective 30hapter 2 Results and Discussion 31.1 Synthesis 31.2 Crystal Structures 36.3 DFT Calculations 41.4 Photochemical Properties of Ligands 50.4.1 Electronic Spectra of Ligands 50.4.2 Quantum Yields and Lifetimes for Ligands 55.5 The Photochemical Properties of Complexes 58.5.1 Electronic Spectra of Complexes 58.5.2 Quantum Yields and Lifetimes for Complexes 73.6 Synthesis of Bridged Stilbene 75hapter 3 Conclusion 79hapter 4 Experimental Section 80.1 Chemicals 80.2 Methods and Instruments 83.2.1 Nuclear Magnetic Resonance, 400 MHz ; Varian 400 or Bruker 400 83.2.2 FT-Infrared Spectrometer ; Varian 640-IR 83.2.3 Elementary Analyzer ; Elementar Vario EL III 84.2.4 High-Resolution MASS 84.2.5 X-Ray Single Crystal Diffractometer 84.2.6 Melting Point Equipment ; Mel Temp II 84.3 Photophysical Methods 85.3.1 UV-Vis Absorption Spectra 85.3.2 Fluorescence Quantum Yield Measurement 85.3.3 Fluorescence Decays 86.3.4 Phosphorescence Spectra 86.3.5 Phosphorescence Decays 86.3.6 Quantum Yield of Photoisomerization 87.3.7 Density Functional Calculation 87.4 Synthesis Procedure 88.4.1 General Procedure 88.4.2 Synthesis and Identification of 4-(N, N–dimethylamino)styrene 90.4.3 Synthesis and Identification of 4-(N, N-diphenylamino)styrene 91.4.4 Synthesis and Identification of 2-(3-bromophenyl)pyridine 93.4.5 Synthesis and Identification of 4-bromo-2-phenylpyridine 94.4.6 Synthesis and Identification of Ligands 96.4.7 Synthesis and Identification of Complexes 99.4.8 Synthesis and Identification of 5-diphenylaminoindene 103hapter 5 References 107ppendix
Strategy of Integrated Marketing Communication of luxury housing[Sky Garden of Huaku] as an example
No full text在過去對於整合行銷傳播的研究都在於「整合的內容」、「不同策略層級的整合」方面進行探討及研究。目前具有實務經驗並對於房地產整合行銷傳播加以進行研究的文獻相對其他產業來的少，針對高端住宅市場的整合行銷傳播研究更是付之闕如。本研究主要研究目的欲探討:1.整合行銷傳播與房地產行銷之關聯性2.近年房地產總體經營環境，對房地產行銷造成之結構性轉變如何3.高端住宅行銷如何應用整合行銷傳播模式，以創造更高的顧客價值。 本研究結果發現:(一)房地產業整合行銷資源整合必需拉高到產業供應鏈整合層級且為常態。(二)房地產業中產業供應鏈、人員組織、行銷機能的整合實為一套系統間的整合。(三)台灣高端住宅市場是房地產第五次景氣循環多頭市場下的時代產物。 (四) 高端住宅市場受到政府政策介入影響甚深，整合行銷力有未逮。(五)高端住宅除地段外，建築團隊的對於潛在顧客的整合行銷溝通決定個案的成敗。(六)高端住宅的溝通方式少用一般大眾媒體，感動服務及體驗行銷成為溝通重點。 本研究貢獻:針對高端住宅市場的整合行銷傳播提出以下建議，作為未來高端住宅在個案銷售執行方面的重要參考依據: 一、高端住宅房地產整合可從戰略層級到戰術層級加以整合，也就是從「產業供應鏈整合」、「人員組織整合」到「行銷機能整合」三大整合，但本研究進一步提出房地產整合行銷傳播「系統觀點」，其實上述三大整合其實為一套系統間的整合，彼此密不可分。 二、三大部門「研展部」、「企劃部」、「業務部」與六大行銷機能「市場分析機能」、「產品定位機能」、「廣告表現機能」、「媒體運用機能」、「業務銷售機能」、「顧客滿意機能」整合模式為日後業界可參考之個案操作模式。 三、雙引擎行銷模式適用於目前高端住宅市場，解決當前台灣房地產所面臨的四大挑戰，包括政策、社會、需求及供給等問題，新境界行銷館可以複製並留下高端住宅的成功模式，打造尊榮空間、進行數位化展示與典藏，並成為之後高端住宅公司提案簡報的重要實績，整合個案已投入資源，而這樣的行銷策略，也能符合當今永續、環保、節能的社會趨勢。In the pass, all the research we have for [strategy of Integrated Marketing Communication] was focus on researching [how we organized] and [different level of organized]. The research which involved testing and experiment for real estate is relatively speaking rare, not to mention about the high end luxury market. This research is mainly focus on: 1. The relation between strategy of Integrated Marketing Communication and real estate. 2. The real estate environment in the reason years, and how strategy turns the Marketing. 3. How can we apply strategy of Integrated Marketing Communication on high end luxury market? 4. Through the research we have done, we discover that; 1. In able to combine Integrated Marketing Communication on real estate, the high levels of supply chain must become usual. 2. The middle part of the supply chain must bond to a complete system. 3. The high end luxury market in Taiwan was created by the fifth cycle of real estate economy. 4. The government also highly involved in high end luxury market. 5. As for high end luxury market, the building team will be as important as with the location. 6. The communication for selling the high end luxury building is very unordinary. Contribution of this research: have suggestion which target directly to high end luxury market, that for build a foundation of the future goal. 1. The strategy of Integrated Marketing Communication for high end luxury market can be start from strategy to tactical, which means from industrial supply chain, human organization Integrate to the function of strategy of Integrated Marketing. However in this research we discover yet another fact, and that is systematic view, which play the role between the three critical point above. 2. 3 key department [marketing department], [planning department] and sales department] along with 6 marketing function [marketing research], [product positioning], [advertisement], [media usage], [selling] and [customer satisfaction] will be the example for the companies to run the case. 3. So call [double engine] of selling strategy is currently suite for high end luxury market in Taiwan. It solve 4 biggest challenge that the company can face, which include policy, society, demand and supply. Our selling center [NEW GATE] can copy and store successful case in digital way. Have a luxury place digital demonstration, this will become a good foundation and data base for future cases, and this is also good for environment protection, which suite for today’s slogan
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
