“…Inset: RTP intensity changes at 667 nm after addition of n-Bu3N and CF3COOH to 41a and 41b, over six cycles (λex = 370 nm). [54] 通过分子结构的精细设计和发色团的合理引 入,具有酸碱刺激响应的轮烷体系还可以实现磷光 的开启和关闭。2016 年,田禾课题组 [54] 就利用酸碱 [55] Figure 18 (a) Schematic illustration of dual-stimulus-driven reciprocating motions of the [3]rotaxanes.

“…of TFA in filter paper. [55] 第一例基于机械互锁分子的力致发光体是由 Sagara 和 Weder 等于 2018 年报道的 [60] , 他们受到了 Stoddart 等人工作的启发 [61] , 将具有电子转移效应的 NDI 和苯并噻二唑(BTH)引入 [ 电化学氧化还原调控也是一类经典的刺激响 应机制 [66] , 1998 年 Stoddart 课题组 [67] 利用四硫富瓦 烯的氧化还原性质,通过添加氧化剂和还原剂实现 了 [2]索烃中 CBPQT 4+ 在另一大环上的可逆相对运 动。2022 年,他们又利用类似的机制 [68] ,改变识别 [62] 除了上述的轮烷体系之外,索烃也可以作为具 有刺激响应性的机械互锁分子实现化合物发光性质 的可控变化。一般来说,调节索烃分子内的多种共 构象相对稳定性将有利于不同发光行为的表达,在 索烃体系中具有与轮烷类似的调控机制。2021 年欧 阳灏宇课题组 [69] 利用锌离子的可逆配位作用和溶剂 极性的调控实现了芘激基缔合物发射的开启与关闭 (图 25a)。他们将邻菲啰啉基元引入索烃骨架中, to the indicated strains (left) and subsequent relaxation from the maximum strain of 600% (right).
