Phase behaviour and crystal structures of 2′,3′-difluorinated p-terphenyl derivatives
No full textThe crystal structures of difluorine derivatives of p-terphenyls (nTm) have been determined by single-crystal X-ray diffraction. For the unsymmetrical substituted compounds 2′,3′-difluoro-4-methyl-p-terphenyl (1T0, C19H14F2) and 4-ethyl-2′,3′-difluoro-4′′-methyl-p-terphenyl (1T2, C21H18F2), the crystal structure is disordered, with molecules statistically entering the crystal in up and down orientations, with full superposition of all the atoms, except for those of the terminal groups (H/methyl for 1T0 and methyl/ethyl for 1T2). For triclinic 2′,3′-difluoro-4,4′′-dimethyl-p-terphenyl (1T1, C20H16F2), with the space group P , the two crystallographically independent molecules have the same conformation, which is different from monoclinic 1T0 (space group C2) and 1T2 (space group C2/c). A common feature of the conformation of the three compounds is the noncoplanar twisted arrangement of the three rings of the p-terphenyl moiety. Two-dimensional (2D) Hirshfeld fingerprint plots are consistent with H ... H and C ... H contacts in the crystal packing. For the three compounds, the phase behaviour has been investigated by POM (Petra/Osiris/Molinspiration) and differential scanning calorimetry (DSC) analysis. 1T2 is mesogenic, with enantiotropic nematic behaviour
Cuticular hydrocarbon analysis for the identification, ageing and geographical variations of forensically important blowflies
No full text© Cranfield University 2022. All rights reserved. No part of this
publication may be reproduced without the written permission of the
copyright ownerCalliphoridae (blowflies) are important for forensic entomology as they are often the first
group of insects to inhabit decomposing remains. To estimate the minimum post-mortem
interval (PMImin), blowfly samples are collected from the crime scene and identified, and
then the age needs to be determined for each species. Accurate species identification is
crucial, as varied species have different life-stage timings. Previous studies on Diptera
have shown the possibility of using cuticular hydrocarbon (CHC) analysis to aid species
identification, ageing and ultimately calculating PMImin. However, since prior research
was conducted at constant temperatures, the effect of fluctuating temperature on chemical
profiles and the stability of CHCs in the field remains unclear. This thesis aims to examine the CHC profiles of Lucilia sericata and Calliphora vicina
reared outdoors in the United Kingdom, Germany and Turkey in terms of species, age
and inter-population differences. The first study investigates whether the stability of the
CHC profiles of two colonies reared outdoors can be used to identify species-specific
characteristics. The second examines the effects of fluctuating and constant temperatures
on the CHC profiles of the life cycle stages and the use of their chemical profiles for age
estimations. The final study aims to determine the differences in CHC profiles of the same
species living in different habitats and whether they can be used to distinguish
populations. The CHC profiles of the samples were extracted and analysed using Gas
Chromatography-Mass Spectrometry (GC-MS). The statistical interpretation was carried
out using Principal Component Analysis (PCA). The results showed that CHC profiles
differed significantly between developmental stages by species, age, rearing temperature
and geographical location. This study highlights that despite environmental factors
affecting the stability of CHC compositions, the CHC analysis can be used as a
complementary tool for identifying and ageing the species. Furthermore, the effects of
ambient temperature and geographical variation on CHC profiles may be useful for
determining inter-population variations.Ph
