摘要：

Photochromic properties of sulfonated spiropyran (SP-SO3-) incorporated within a silica matrix by the sol-gel route were studied. The existence of organic anions such as p-toluene sulfonic acid (PTS), dodecylbenzene sulfonic acid (DBS) was essential for stable and reversible photochromism. In the case of DBS/SP-SO3- (mole ratio = 50.0), the most stable and reversible photochromic properties were attained among them. (C) 1997 Elsevier Science B.V.
