A series of novel thiophene-substituted aza-BODIPY dyes were synthesized by means of a standard procedure and complemented by a Stille-coupling of a brominated species with 2-tributylstannylthiophene. The optical as well as the electrochemical properties of the compounds were investigated and compared to result of density functional theory (DFT) calculations. The influence of the thiophene substituents
通过标准方法合成了一系列新颖的噻吩取代的氮杂-BODIPY染料,并补充了溴化物种与2-三丁基锡烷基噻吩的斯蒂勒偶联。研究了化合物的光学和电化学性质,并将其与密度泛函理论(DFT)计算的结果进行了比较。讨论了噻吩取代基的影响,取决于关于HOMO和LUMO前沿轨道的aza-BODIPY核心位置。BODIPY核上HOMO和LUMO系数的不同分布会导致噻吩取代基对HOMO和LUMO能量产生可变影响,这是可调光学和电化学性质的起源。
