Solvent-tuned charge-transfer properties of chiral Pt(ii) complex and TCNQ˙⁻ anion adducts

Abstract

A new couple of charge transfer adducts comprising of one chiral Pt(ii) complex cation together with one TCNQ˙− anion have been prepared, and solvent-induced variances of absorption, luminescence as well as chiral spectra have been investigated.

Sorting Phenomena and Chirality Transfer in Fluoride-Bridged Macrocyclic Rare Earth Complexes

“…Chiral sorting corresponds to enantiomeric self-recognition or enantiomeric self-discrimination, and these processes have been documented for supramolecular systems, − metal complexes, − and organic systems, including macrocyclic compounds. − Chiral sorting phenomena are most often demonstrated for solid state, while examples of enantiomeric self-recognition well documented for solutions of metal complexes are less common. Another important issue in the synthesis of elaborate enantiopure metal complexes or supramolecular assemblies is chirality transfer, − e.g., the transmission of chiral information from enantiopure ligands to metal centers. While there are many chiral transition metal complexes with well-defined stable configurations, the control over chirality of lanthanide complexes, in particular polynuclear complexes, − ,− is more difficult due to the lack of spatial preferences, lability, and high-coordination numbers of these ions.…”
