ized [2]rotaxane with a 4-morpholin-naphthalimide fluorophore as stopper was designed, synthesized, and studied. The macrocycle can shuttle reversibly in response to external acid–base stimuli and the spiropyran functional group can be switched to its ring-opened merocyanine (MC) state. It has been shown that, by introducing two spiropyran units into the system, intercomponent interactions, such as
本文设计,合成和研究了以4-吗啉-萘二甲酰亚胺荧光团为阻滞剂的双螺并吡喃官能化的[2]轮烷。大环化合物可响应外部酸碱刺激而可逆穿梭,并且螺吡喃官能团可切换至其开环的花菁(MC)状态。研究表明,通过将两个螺吡喃单元引入系统中,SP或MC功能单元与荧光团之间的组分间相互作用(例如电子转移和能量转移过程)可以响应于酸碱的结合而发生变化。和光化学刺激,可以产生明显的紫外线/可见光吸收和荧光光谱变化。
