benzothiazoles, and their spectroscopic and photophysical properties in solutions were investigated. The derivatives showed solvatochromic fluorescence with quantum yields over 0.68 in various organic solvents similar to the core fluorophore structure. The color variation ranges in fluorescence solvatochromism of the derivatives were wider than that of the original compound having the core structure, 6-dimethyl
制备了一系列在2-苯基上具有羧基,酯和酰胺取代基的6-二甲基氨基-2-苯基苯并噻唑,作为一系列推挽式苯并噻唑,并对其在溶液中的光谱和光物理性质进行了研究。这些衍生物在类似于核心荧光团结构的各种有机溶剂中显示出溶剂化变色荧光,量子产率超过0.68。衍生物的荧光溶剂变色的颜色变化范围比具有核心结构的原始化合物6-二甲基氨基-2-苯基苯并噻唑的颜色变化范围宽。还发现,衍生物与原始化合物一起根据其晶体结构显示固态荧光。尤其是,具有保护的丝氨酸的酯衍生物具有合理的晶体堆积,导致荧光效率增加。本研究的结果为设计在溶液和固态中显示荧光的推挽式2-苯基苯并噻唑提供了指导。
