(meta)stable states is crucial for the development of smart solid‐state luminescent materials. However, the design of luminophores with tunable aggregation states is remaining a grand challenge. Herein, we present a family of mechanochromic luminophores with tunable metastable states, based on the dynamically controllable π–π stacking of the flexible π‐conjugated structure of 2,5‐diarylamino‐terephthalates
不同的热力学(的生成元)的稳定状态是智能固态发光材料的发展至关重要。然而,具有可调聚集态的发光体的设计仍然是一个巨大的挑战。在此,我们基于固态的2,5-二芳基氨基-对苯二甲酸酯的柔性π共轭结构的动态可控π-π堆叠,提出了具有可调亚稳态的机械变色发光体家族。实验数据表明,动力学控制的亚稳态和热力学控制的稳定态都可以通过调节分子间的相互作用(例如π-π堆积和氢键)来生成。结果,成功地实现了这些发光体的高度灵敏的机械刺激响应。
