The design and synthesis of new fluorescent dyes with emission range at 490–650 nm are described. Their structural and electronic properties have been characterized by both experimental techniques and quantum‐chemical calculations. The chromophores are donor–π‐bridge–acceptor push–pull compounds with a π bridge of phenyl and thiophene rings and their combination. Compared with previous thiophene fluorophores
介绍了新型荧光染料的设计和合成,该染料的发射范围为490–650 nm。它们的结构和电子特性已通过实验技术和量子化学计算进行了表征。发色团是具有苯基和噻吩环的π桥的供体-π-桥-受体推挽化合物及其组合。与以前的噻吩荧光团相比,这些染料在吸收和发射光谱中显示出明显的红移,并提供紧凑的红色发光荧光团。该染料具有氨基琥珀酰亚胺基活性酯,可以很容易地与蛋白质,聚合物和其他含氨基的物质结合。
