routes. These compounds have been fully characterized by EA, IR, NMR and MS. The electronic absorption and fluorescence of these compounds have been systematically investigated for the first time. The relationships between their photophysical properties and structures have been discussed. The alteration of absorption and emission wavelengths can be elucidated by Hammett's substituent constants.
雅各布森(Jacobson)在三种不同的途径下,通过雅各布森(Jacobson)将
2-氨基苯硫醇与
苯甲酰氯或
苯甲醛衍
生物进行环合缩合,制备了一系列高产的新型2-芳基
苯并噻唑。这些化合物已通过EA,IR,NMR和MS进行了全面表征。首次系统地研究了这些化合物的电子吸收和荧光。已经讨论了它们的光物理性质和结构之间的关系。吸收和发射波长的变化可以通过哈米特的取代基常数来阐明。
