Facile Formation of Stable Crystals with Gold-like Metallic Luster from Organic Molecules: 1-Aryl-2-(2-thienyl)-5-[5-(tricyanoethenyl)-2-thienyl]pyrroles
Facile Formation of Stable Crystals with Gold-like Metallic Luster from Organic Molecules: 1-Aryl-2-(2-thienyl)-5-[5-(tricyanoethenyl)-2-thienyl]pyrroles
A newclass of π-conjugated organiccompounds, 1-aryl-2,5-bis[5-(tricyanoethenyl)-2-thienyl]pyrroles that form gold-like lustrous crystals with a high melting point were obtained. The molecules in these crystals are arranged in a planar sheet to get close to each other via the intermolecular CH⋯N hydrogen bond between the cyano nitrogen and the hydrogen of the nearest thiophene or pyrrole ring, which
