Spectrochim Acta A Mol Biomol Spectrosc. 2001 Jan;57(1):149-54. doi: 10.1016/s1386-1425(00)00353-x.

Abstract

The photochromism of Schiff bases N,N'-bis(salicylidene)-1,2-diaminoethane (BSE) and N,N'-bis(salicylidene)-1,6-cyclohexanediamine (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.
