摘要
Abstract
The luminescence and photochromism of a series of six salicylaldehyde-derived Schiff base in solution and solid state were investigated by fluorescence spectroscopy 2,2′-[1,2-phenylenebis (nitrilomethylidyne)] bisphenol(1); 2,2′-[1,4-phenylenebis (nitrilomethylidyne)] bis-phenol(2); 2,2′-[1,2-cyclohexanediylbis (nitrilomethylidyne)] bisphenol (3); 2,2′-[ 1,2-ethane diylbis (nitrilomethylidyne)]bisphenol(4); 2,2′-[1,6-hexanediylbis(nitrilomethylidyne)]bisphenol(5); 2-[(1-phenylethyl)imino]methylidynephenol｝ (6).The experimental results show that the fluorescence intensity of Schiff base 1～6 is related to the structure of the conjugated system or the carbon bridge linking the two fluorophores in the molecules.The time-resolved fluorescence spectroscopy of 1,3－6 show that they are photochromic in either solution or solid state (2 is known as a thermochromic one).The time course fluorescence spectroscopy show that the “macro-response” of Schiff bases 3,5 and 6 with irradiation is extremely rapid,especially for 5,of which the fluorescence intensity changed by about 70％ within 10 s.关键词
