Abstract

Abstract:

3-aminopyridine-2(1H)-thione reacted repectively with Salicylaldehyde and 2-Hydroxy-1-naphthaldehyde to form two Schiff base ligands L1 and L2, following treated by triethylamine and boron trifluoride diethyl etherate to form a new 2-(2'-hydroxyphenyl)pyridothiazole (L3) and two BODIPY compounds B1 and B2. The structure of L3 and B1 have been determined by X-ray diffraction. 2-(2'-hydroxyphenyl)pyridothiazole compound(referred to HPT) exhibits excited-state proton transfer(ESIPT) effect, the effect of solvent polarity on ESIPT was investigated by UV-visible absorption and fluorescence spectra.

Key words: 2-(2’-hydroxyphenyl)pyridothiazole, ESIPT, crystal structure, spectral properties
