Y-shaped D-A type molecules possessed two independent ICT states inside, resulted from the two independent D−A conjugation from their small donor arms to the acceptor. As their two D−A torsion angles are very sensitive to aggregated states, they showed interesting mechano-induced TADF and high-contrast MRL properties.

DA型分子内部具有两个独立的ICT状态,这是由它们的小供体臂与受体的两个独立的D−A缀合产生的。由于它们的两个 D−A 扭转角对聚合态非常敏感,因此它们表现出有趣的机械诱导 TADF 和高对比度 MRL 特性。
