Cavitand-Based Coordination Cages: Achievements and Current Challenges
No full textThe research results obtained in the self-assembly of cavitand-based coordination cages are presented. Cavitands are ideal multidentate ligands for the creation of coordination cages due to their structural rigidity, concave structure, and great versatility in terms of synthetic modularity. The introduction of the ligand moieties on the resorcinarene building block proceeds at the upper rim of the cavity, to take full advantage of the structural rigidity of the cavitand scaffold. Two different synthetic strategies are employed for the formation of multidentate cavitand ligands: (a) functionalization at the apical positions and (b) introduction of the ligands as bridging units. The key features to control the cage self-assembly process emerging from this overview are the preorganization, for the cavitands, and kinetic versus thermodynamic stability of the resulting complexes, for the connecting metal. The versatility of this class of coordination cages is demonstrated by the formation of their heterotopic and heteronuclear versions, as well as their self-assembly on gold and silicon surfaces. Desymmetrization of the cages is appealing because of the resulting differentiation of the inner cavities in terms of shape and interactivity, while surface self-assembly represents an important opportunity to expand the application range of these objects
Self-assembly of a cavitand-based heteronuclear coordination cage
No full textA new self-assembly protocol leading to the formation of heteronuclear coordination cage 10 is reported. Reaction of tetradentate cavitand ligand 1, bearing one ethynylpyridine and three benzonitriles at the apical positions, with Pt(dppp)OTf2 and Pd(dppp)OTf2 in a 1:3 ratio yields 10 as the thermodynamic product. Under the same conditions, the self-assembly of 1 with either Pt or Pd metal precursors gives a mixture of isomeric homonuclear cages 8a-c or 9a-c, respectively
Molecular Recognition with Ditopic Cavitand Re-Complexes
No full textThe synthesis of a series of cavitand receptors bearing increasing numbers of phosphonate groups at their upper rims and of the corresponding Re-based ditopic complexes is reported. The molecular recognition properties of these phosphonate cavitands towards both monotopic and ditopic N-methylpyridinium salts were investigated. The numbers and spatial dispositions of P=O units are pivotal for the complexation of guest ions. The removal of a single P=O bridge from the parent tetraphosphonate cavitand was sufficient to reduce the association constant by almost three orders of magnitude. Elimination of a second P=O unit completely abolished complexation in the AC distal isomer, both in monotopic and in ditopic hosts. The preorganised structure obtained by interconnection of two triphosphonate cavitands through a Re system showed moderate positive self-assembly cooperativity in the inclusion of ditopic N-methylpyridinium salts in both polar and nonpolar solvents. The speciation profile in ethanol indicates that the clamshell 1: 1 complex is dominant at low concentrations (< 10(-4) M) whereas the 1: 2 complex is preferred at higher concentrations of ditopic guest

Synthesis of Partially-Bridged Phosphonate and Thiophosphonate Resorcinarenes
No full textThe synthesis of partially bridged thiophosphonate and phosphonate resorcinarenes is reported in this paper. Resorcinarenes functionalised at the upper rim with two or three P=X (X=S,O) bridges oriented towards the molecular cavity are obtained from the treatment of the corresponding (iiii) tetrasubstituted cavitand with 1,2-dihydroxybenzene and base in DMF. This synthetic route selectively promoted the formation of one of the two disubstituted resorcinarenes, the AC isomer. The crystal structure of the AC-dithiophosphonated resorcinarene 4 has been determined

Validation of the Italian Version of the Rapid Geriatric Assessment in Community-Dwelling Older Adults
No full textBackground/Objectives: The Rapid Geriatric Assessment (RGA) is a tool designed to screen for frailty, sarcopenia, anorexia related to aging, and cognitive impairment. This study aimed to translate and validate the RGA for use among Italian community-dwelling older adults. Methods: This cross-cultural study involved 100 community-dwelling older adults randomly recruited through convenience sampling from general practitioner offices in Genoa (Italy), between January and June 2019. The RGA includes the Simple FRAIL Questionnaire Screening Tool, SARC-F Screening for Sarcopenia, Simplified Nutritional Assessment Questionnaire (SNAQ), and Rapid Cognitive Screening (RCS). These were validated against gold-standard tools: the Abbreviated Comprehensive Geriatric Assessment (aCGA) and Multidimensional Prognostic Index (MPI). Additional assessments included the Timed Up and Go (TUG) and Handgrip test. The validation process included forward–backward translation, synthesis, and consensus by independent reviewers. Psychometric properties, internal consistency (Cronbach alpha), and validity correlations were analyzed. Results: The RGA demonstrated satisfactory psychometric properties, with internal consistency (Cronbach alpha = 0.59) and significant validity correlations (RGA and aCGA, rho = 0.34, p = 0.001; RGA and MPI, rho = 0.49, p < 0.001). Discriminant validity was confirmed by significant correlations between specific subitems and reference measures: FRAIL with TUG (p < 0.05), SARC-F with Handgrip strength (p = 0.013), SNAQ with BMI, and RCS with MMSE (p < 0.001). Conclusions: The Italian version of the RGA is a reliable screening tool for geriatric syndromes in community-dwelling older adults. While it does not replace a CGA, the RGA may identify individuals who may benefit from further evaluation using a complete CGA
