Abstract
This paper presents the results of quantum-chemical and spectral studies on studying fluorescence of binuclear zinc(II)-bis(dipyrrinate)s [Zn2L2] in non-polar and polar environments and their binary mixtures. We studied the efficiency of the fluorescence quenching of fluorophores depending on of isomerism forming their bis(dipyrrine) ligands and an electron-donating ability of the solvent. Found that 3,3â²-bis(dipyrrinato)zinc(II) demonstrates the highest sensitivity of the fluorescence to the presence of the electron-donor component compared with 2,3â²- and 2,2â²-analogs. The results obtained allow to offer helicates [Zn2L2] as new, highly sensitive and selective fluorescent sensors for the detection of N- and O-containing analytes.
