Abstract
Abstract Various 2-aryl-1-(4-methoxyphenyl)-5-(5-tricyanoethenyl-2-thienyl)pyrroles ( 3 ) were synthesized. When the 2-aryl group of 3 is phenyl, 4-tolyl, and 4-methoxyphenyl, organic crystals with greenish yellow metallic luster are formed. In contrast, a 2-(4-fluorophenyl) derivative of 3 gives gold-like lustrous crystals. The relation of their crystal structures with the appearance of metallic color is mentioned.
