We report therein the synthesis and photophysical properties of a new series of two- and tribranched compounds built up from benzene or triphenylamine as central core and electron-withdrawing diazine rings as peripheral group. The arms allowing connection between these two parts are constituted by an ethynylene linker. All these compounds are fluorescent and are of particular interest with generally
我们在其中报告了以苯或三苯胺为中心核和吸电子二嗪环为外围基团构建的一系列新的两支和三支化合物的合成和光物理性质。允许这两个部分之间连接的臂由亚乙炔基连接体构成。所有这些化合物都是荧光的,并且特别令人感兴趣,它们通常具有良好的量子产率和良好的斯托克斯位移。其中一些已经过测试,具有两光子吸收(TPA)特性,并且显示出有趣的性能。
