Abstract：
Two novel chiral molecules, (4S)-5,5-dimethyl-2-(4-oxo-4H-chromen-3-yl)thiazolidine-4-carboxylic acid (OCCA) and (4S)-5,5-dimethyl-2-(4-(1,2,2-triphenylvinyl)phenyl)thiazolidine-4-carboxylic acid (TPCA), were successfully synthesized by aldehyde amine condensation reaction, and their structures were characterized by 1H NMR and single crystal X-ray diffraction. The intensities of photoluminescence changed with the aggregation, exhibiting that OCCA and TPCA are aggregation-induced emission luminogens (AIEgens). After complete aggregation, OCCA emitted the purple-blue light at the peak of 388 nm and TPCA emitted the cyan light at the peak of 488 nm. The aggregation-induced emission (AIE) effects for OCCA and TPCA resulted from local state to twisted intermolecular charge transfer (TICT) and restriction of intramolecular motion (RIM), respectively. Other spectra including UV-vis, IR, and Raman spectra were also discussed in detail.
摘要：
两个新的手性分子，(4S)-5,5-二甲基-2-(4-氧代-4H-色烯-3-基)噻唑烷-4-羧酸(OCCA)和(4S)-5,5-二甲基-2-(4-(1,2,2-三苯基乙烯基)苯基)噻唑烷-4-羧酸(TPCA),通过醛胺缩合反应成功合成,通过1HNMR和单晶X射线衍射对其结构进行了表征。光致发光的强度随着聚集而变化，表明OCCA和TPCA是聚集诱导的发光原(AIEgens)。完成聚合后，OCCA在388nm的峰值处发射紫蓝光,并且TPCA在488nm的峰值处发射青色光。OCCA和TPCA的聚集诱导发射（AIE）效应是由局部状态到扭曲的分子间电荷转移（TCT）和分子内运动（RIM）的限制引起的，分别。其他光谱，包括UV-vis，IR,并详细讨论了拉曼光谱。
