G. Pistolis et al., PHOTOACTIVITY WITHIN CYCLODEXTRIN CAVITIES - INCLUSION COMPLEXES OF ANILS WITH CYCLODEXTRINS, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 242, 1994, pp. 215-219
Complexation of the thermochromic compounds N-5-chloro-salicylideneani
line and N-salicylidene-2-aminopyridine with cyclodextrins results in
disappearance of thermochromic properties and appearance of photochrom
ism. From uv, visible and fluorescence spectra in the crystalline stat
e and supporting evidence from NMR spectra in solution the structure o
f the complexes is proposed.
