(E)-Ethyl 2-cyano-3-(4′-(diphenyl amino)-[1,1′-biphenyl]-4-yl) acrylate (RSJ) is a novel luminogen based on triphenylamine. It has been fully synthesized and characterized, exhibiting an incredible photophysical phenomenon known as aggregation-induced emission (AIE). This work describes a fluorescent sensor that detects vitamin B2 in mixed aqueous media with high selectivity and a low limit of detection
( E )-2-氰基-3-(4'-(二苯基氨基)-[1,1'-联苯]-4-基)丙烯酸乙酯(RSJ)是一种基于三苯胺的新型发光剂。它已被完全合成和表征,表现出令人难以置信的光物理现象,称为聚集诱导发射(AIE)。这项工作描述了一种荧光传感器,能够以高选择性和低检测限检测混合水介质中的维生素 B2,以及可逆机械致色发光的机制。此外,通过组织毒理学研究验证了该分子在水中的无毒性。接受两种不同浓度“新型发光体”的鱼在混合水介质中感知维生素 B2(核黄素)时表现出光物理现象,但其肝脏、肾脏、鳃、大脑和肌肉的结构组成没有表现出任何显着差异组织与对照组相比。
