Investigation of Dual Fluorescence in 4-Dimethylaminobenzonitrile

  • Published:
Russian Physics Journal Aims and scope

Abstract

A quantum-chemical study of the fluorescent properties of a 4-dimethylaminobenzonitrile molecule is performed with allowance for the interaction with a polar solvent. It is shown that two radiative states are formed and no significant changes occur in the geometry of the molecule. The mechanism of formation of anomalous dual emission for polar molecules is discussed. It is suggested that the interaction between a polar molecule and a polar solvent results in a strong hydrogen bond and a molecule-polar solvent complex where two radiative processes of different nature are possible.
