QUINAZOLINONE DERIVATIVES: SYNTHESIS AND LUMINESCENCE PROPERTIES

Abstract

Benzazines are widely studied heterocyclic compounds1 its framework possesses strong electron withdrawing ability and can be used as acceptor fragment to form push-pull molecules with ITC character. Quinazolin-4(3H)-one 1 represent promising fluorescence molecule with quantum yield 71% in toluene.2 2-(2-Hydroxyphenyl)quinazolin-4(3H)-ones can serve as N, O-chelating ligand favorable for construction BF2 complexes 2.3 The introduction of methoxy group at para-position of phenol ring leads to increase in quantum yield compared to unsubstituted counterpart (from 24 to 70%).
