Dual fluorescence of 2 4 n n dimethylaminophenyl imidazo 4 5 b pyridine effect of homogeneous and microheterogeneous environments

Abstract

Intermolecular charge transfer ICT is a common excited state phenomenon that occurs in several photochemical and photobiological processes Organic molecules those consist of an electron donor and acceptor pair linked by a single bond may undergo ICT in the excited state Such bichromophore compounds have received considerable attention as possible models for the investigation of the primary function of photoelectric devices and chemical energy storage Though several models are proposed to ex
