摘要:

分别使用水杨醛和2-羟基-1-萘甲醛与2-巯基-3-氨基吡啶反应得到了希夫碱配体L1L2,在三乙胺和三氟化硼乙醚的反应条件下得到了2-(2’-羟基苯基)吡啶并噻唑配体L3和氟硼化合物B1B2,通过X-射线单晶衍射分析确定了L3B1的晶体结构。2-(2’-羟基苯基)吡啶并噻唑类化合物(简称HPT)是一类具有激发态质子转移(ESIPT)效应的有机分子,本文通过紫外可见吸收光谱和稳态荧光光谱研究了溶剂极性对ESIPT效应的影响。

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.
