Research Abstract

[3] Catenanes, which change their color according to external stimuli such as temperature and metal ions, were investigated.[3] Catenanes having chromophores were synthesized. On addition of diamine to their solution, UV spectra changes of their solution were observed with a couple of isosbestic points. Variable-temperature fluorescence spectra showed red shift of emission maximum with increasing temperature.
