Photochromic dihetarylethenes. 12.* Synthesis of 5-alkyl-2- (1,3,4-oxadiazol-2-yl)thiophenes and their photochromic derivatives
Photochromic derivatives of 5-alkyl-2-(1,3,4-oxadiazol-2-yl)thiophenes have been synthesized for the first time. Their photochromic and fluorescent properties have been studied.
