(4-Biphenylyl)phenyldibenzofulvene is weakly luminescent in the amorphous phase but becomes highly emissive upon crystallization; this unusual crystallization-induced emission enhancement effect allows its emission to be repeatedly switched between dark and bright states by fuming-heating and heating-cooling processes.
(4-二苯基)苯基
二苯并呋喃在非晶态下发光较弱,但在结晶后发光强度显著增强;这种不寻常的结晶诱导发光增强效应使其发光可以通过熏热和加热冷却过程在暗态和亮态之间反复切换。
