A new piezofluorochromic aggregation-induced emission compound was synthesized. The compound had morphology-alterable emission property and its amorphous and crystalline aggregates with various emissions were obtained through evaporation from the solutions in different solvent systems. The spectroscopic properties and morphological structures of the compound were reversed upon pressing and annealing
合成了一种新的压电致变色团聚诱导的发射化合物。该化合物具有形态可改变的发射性质,并且通过从不同溶剂系统中的溶液蒸发而获得了具有各种发射的无定形和结晶聚集体。在压制和退火(或发烟)后,该化合物的光谱性质和形态结构被颠倒。结果表明,在外部压力下,通过晶体-非晶相变产生了压电氟致变色性质。相变的原因归因于分子的扭曲构象,其导致差的固体分子堆积和在层状层的界面中形成一些空腔,如通过单晶X射线衍射分析所证实的。
