✦ Synopsis

Studies on the fluore~ence and direct inns-cis photoisomeriz.aGon of 4.4'-diaminostilhene in a vnrir~y or solvents. indicate a marked efrect of solvent polarity. With increasing solvem polarity [here is a decrease in lluorescence yield nod MeGme and an increase in the rate 01 phoh%sometization. The resuhs are discussed in Icrms or a polariIy erfecl on the cncr~y barrier IO pholoiscimerization.
