Aggregation-induced emission enhancement of anthracene-derived Schiff base compounds and their application as a sensor for bovine serum albumin and optical cell imaging.
本研究以9-蒽羧醛分别与苯肼、4-苯基半缩脲和4-苯基硫代半缩脲缩合,合成三种蒽基席夫碱化合物R1–R3,并通过紫外-可见吸收、荧光、红外、核磁共振和质谱等技术表征。通过延长π共轭,R1–R3的吸收光谱红移至可见区。由于激发态C=N双键快速异构化,R1–R3在四氢呋喃(THF)中荧光较弱;在THF/水混合体系中逐渐加入水至90%时,...
