QUINAZOLINONE DERIVATIVES: SYNTHESIS AND LUMINESCENCE PROPERTIES
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%).This work was supported by the Russian Foundation for Basic Research (grant # 19-33-90014)

Synthesis and fluorescent properties of 2-styryl-6,7-difluoro-8- hydroxyquinoline and its Zn(II) complex
A synthetic approach to 2-methyl-6,7-difluoro-8-hydroxyquinoline, a key intermediate, has been developed. 6,7-Difluoro derivative of 2-styryl substituted 8-hydroxyquinoline and its Zn(II) complex have been obtained. Effects of fluorine atoms in the benzene ring on photophysical properties of 2-styryl-8-hydroxyquinolines and their Zn(II) complexes have been studied. © 2013 Elsevier B.V
