自2011年发现大多数聚集诱导发光（aggregation-induced emission，AIE）分子具有机械响应发光（mechano-responsive luminescence，MRL）以来，关于AIE分子MRL的研究受到了广泛关注，并且这一领域得到了极大的发展。四苯乙烯（TPE）作为研究最广泛的AIE核之一，已被广泛用于构建MRL分子。本文综述了具有AIE特性的TPE衍生物的MRL研究进展，包括机械响应型AIE活性材料的发展历史、MRL机理研究、基于TPE的机械响应型发光材料、含有多个AIE活性单元的机械响应型发光材料、TPE衍生物的机械记忆变色和机械发光。此外，本次审查将提供一个角度对可能存在的机会和未来的挑战，在这一研究领域。
Since the realization in 2011 that most aggregation-induced emission (AIE) molecules exhibit mechano-responsive luminescence (MRL), research regarding the MRL of AIE molecules has drawn much attention, and this area has been expanding tremendously. As one of the most extensively studied AIE cores, tetraphenylethylene (TPE) has been widely used to construct MRL molecules. This review will focus on recent advances in MRL of TPE derivatives with AIE properties, including a brief history of mechano-responsive AIE-active materials, mechanistic studies on MRL, mechano-responsive luminogens based on TPE, mechano-responsive luminogens containing multiple AIE-active units, mechano-memory chromism and mechanoluminescence of TPE derivatives. Moreover, this review will give a perspective on the possible opportunities and future challenges that exist in this research area.
