reactions is reported. The target is an effective aggregation‐induced emitter. It is photostable with respect to electrocyclization, due to the presence of the fluorine substituents. This compound undergoes photochemical trans/cis isomerization of its styryl double bonds.
据报道,使用包括狄尔斯-阿尔德和霍纳反应在内的常规合成顺序合成了2,3,5,6-四(2,6-二氟苯基)二(苯乙烯基)苯。目标是有效的聚集诱导的发射体。由于存在氟取代基,因此对于电环化是光稳定的。该化合物的苯乙烯基双键经历光化学反式/顺式异构化。
