title: Formation of gold-like metal-lustrous inclusion crystals from 1-phenyl-2,5-bis[5-(tricyanoethenyl)-2-thienyl]pyrrole host and an electron-donating aromatic guest.
abstract: A novel pi-conjugated organic compound, 1-phenyl-2,5-bis[5-(tricyanoethenyl)-2-thienyl]pyrrole, which bears two powerful electron-withdrawing tricyanoethenyl substitutents, readily yielded gold-like metal-lustrous inclusion crystals with a series of aromatic guest molecules such as toluene, p-xylene, anisole, dimethoxybenzenes and indene. All the inclusion compounds have a common stoichiometric ratio (host/guest) of 2 : 1. X-Ray structural analyses demonstrate that the structural feature for toluene included crystal is similar to those containing p-xylene, anisole, dimethoxybenzenes and indene.
