Spectroscopy study on the photochromism of Schiff Bases N,N '-bis(salicylidene)-1,2-diaminoethane and N,N '-bis(salicylidene)-1,6-hexanediamine

摘要

The photochromism of Schiff bases N,N'-bis(salicylidene)-1,2-diaminoethane (BSE) and N,N'-bis(salicylidene)-1,6cyclohexanediamine (BSH) was studied by steady-state and time-dependent fluorescence, UV-Vis absorption spectroscopy and theoretical chemistry calculations. The experimental results show that BSH can perform the photochromism easier than BSE, may be due to the molecular topology difference. (C) 2001 Elsevier Science B.V. All rights reserved.
