新 gelator 1 基于 tetraphenylethylene (TPE ) 和 diphenylalanine 被设计并且综合。化合物 1 在答案是非放射性的,但是它的荧光在胶化的形成以后打开了,由于导致聚集的排放(AIE ) TPE 的特征。有趣地,荧光是在胶化大音阶的第五音转变之上的 reversibly 交换的开关。扫描电子显微镜(SEM ) ,共焦的激光扫描显微镜(CLSM ) 和 X 光检查衍射(XRD ) 被采用学习胶化。
A new gelator 1 based on tetraphenylethylene (TPE) and diphenylalanine was designed and synthesized. Compound 1 was non-emissive in solution, but its fluorescence turned on after the formation of gels, due to the aggregation-induced emission (AIE) feature of TPE. Interestingly, the fluorescence was reversibly switched "on-off' upon the "gel-sol" transition. Scanning electron microscope (SEM), confocal laser scanning microscope (CLSM) and X-ray diffraction (XRD) were employed to study the gels.
