Синтез и оптические свойства 4-арилпиримидинов хромофоров D-A типа

Abstract

The set of 4-aryl(hetaryl)pyrimidines, where aryl/hetaryl is a highly electron donating substituent was synthesized. Optical and electrochemical properties of the synthesized compounds were studied and the values of a forbidden band gap energy ( ) were determined. The narrowest bandgap was found to be inherent to 4-ferrocenylpyrimidine ( 1.8 eV) and the most long-wavelength emission maximum ‑ to para-substituted pyrimidine which structure embeds a thiophene moiety between N-hexylcarbazolyl fragment and the pyrimidine core ( 577 нм ).
