An original design of a fluorescent dithienylethene (DTE)-based bipyridine, where donor (D) and acceptor (A) groups are located on the same thiophene ring of the DTE unit, is reported; in non-polar solvents, UV or visible excitation triggers a photochromic reaction, disrupting the conjugation and quenching the fluorescence.
                                    报告了一种基于二
噻吩(DTE)的荧光双
吡啶的原创设计,其中供体(D)和受体(A)基团位于 DTE 单元的同一个
噻吩环上;在非极性溶剂中,紫外线或可见光激发会引发光致变色反应,破坏共轭并淬灭荧光。
