以苯并噻唑为电子受体 ,以双苯乙烯基为共轭桥链 ,分别以二甲基胺和咔唑为电子给体合成了 2个新的有机化合物 DMSSB(反式 ,反式 - 2 - {4- [( 4- N ,N -二甲基胺 )苯乙烯基 ]苯乙烯基 }- 1,3-苯并噻唑 )和CSSB(反式 ,反式 - 2 - {4- [( 4- N -咔唑 )苯乙烯基 ]苯乙烯基 }- 1,3-苯并噻唑 ) .用 X射线衍射方法测定了 CSSB的晶体结构 .用波长为 80 0 nm的激光激发时 ,DMSSB与 CSSB在 THF中分别发出强的上转换橙色 ( λm ax=589nm)和蓝绿色荧光 ( λmax=4 88nm) . 2个化合物在不同溶剂中的光物理数据和理论计算结果表明 ,苯并噻唑基是一个很好的电子受体 .
Two new organic compounds, DMSSB (trans, trans - 2) were synthesized by using benzothiazole as electron acceptor and bisstyryl as conjugated bridge and dimethylamine and carbazole as electron donors respectively. Trans-trans- 2 - {4- [(4-N, N-dimethylamine) styryl] styryl} -1,3-benzothiazole) and CSSB 4 - N - carbazole) styryl] styryl} - 1,3 - benzothiazole). The crystal structure of CSSB was measured by X-ray diffraction method. When excited by a laser with a wavelength of 80 0 nm, The strong up-conversion orange (λm ax = 589nm) and blue-green fluorescence (λmax = 488nm) of CSSB in THF respectively.The photophysical data and theoretical calculations of two compounds in different solvents show that benzothiazolyl is A good electron acceptor.
