本文介绍了以4-氨基邻苯二甲酰亚胺2为荧光基团的苯并-18-冠-6-醚-1与苯并-18-冠-6-醚形成的光致变色超分子配合物的设计、制备、表征和性质。超分子络合物1.2的光转化伴随着以开放形式为主的TC形式的出现，这与室温下开放形式的单指数漂白曲线一致。与游离苯并吡喃1相比，在2的存在下，漂白速度提高了5~6倍。从合成的角度来看，改变超分子络合物中的组分更有利于获得具有所需特性的体系。因此，这项研究表明，超分子方法对于包含光致变色和荧光成分相互影响的体系是有前景的。
We present here design, preparation, characterization, and properties of a photochromic supramolecular complex of benzopyran containing benzo-18-crown-6-ether 1 with 4-aminonaphthalimide 2 as a fluorophore. Phototransformation of the supramolecular complex 1.2 is accompanied by the appearance of a predominantly open TC form, which is consistent with the monoexponential bleaching curve of an open form at room temperature. Compared with free benzopyran 1, the bleaching rate is increased by 5-6 times in the presence of 2. From a synthetic point of view, varying the components in the supramolecular complex is more preferable to obtain a system with the desired characteristics. Thus, this study demonstrates that the supramolecular approach is promising for systems that contain photochromic and fluorescent components that influence each other.
