The substitution patterns in fluorinated tetraphenylethenes affect the emission properties, mechano- and thermofluorochromism, compared to those of the parent TPE.
氟化四苯基乙烯中的取代模式影响其发射特性、机械和热致变色性能,与母体TPE相比有所不同。
Halogenated tetraphenylethene derivatives show an anomalous anti-heavy-atom effect where introducing heavy halogens into the typical AIEgen greatly improves the fluorescence quantum yield upon aggregation, and a self-reversible mechanochromism.
