摘要： 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800nm的激光激发时,DMSSB与CSSB在THF中分别发出强的上转换橙色(λmax=589nm)和蓝绿色荧光(λmax=488nm).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.

Abstract: Two novel organic compounds with benzothiazolyl as π electron acceptor, dimethylamino and carbazolyl respectively as π electron donor: DMSSB(trans, trans-2-{4-[4-(N,N-dimethylamino)styryl]styryl}-1,3-benzothiazole) and CSSB(trans, trans-2-{4-[(4-N-carbazolyl)styryl]styryl}-1,3-benzothiazole) were synthesized. The crystal structure of CSSB was determined by X-ray diffraction method. Pumped by 800 nm laser, DMSSB and CSSB respectively exhibited strong up-converted orange(λmax=589 nm) and blue-green(λmax=488 nm) fluorescence in THF, large two-photon absorption cross-section and large two-photon fluorescence emission cross-section. The photo-physical data in various solvents and theoretical calculation results indicate that benzothiazolyl is a good electron acceptor.

Key words: Benzothiazolyl, Up-converted fluorescence, Emission cross-section, DMSSB, CSSB
