A 1-substituted 2,5-dithienylpyrrole derivative having the following formula (I).
in which R is hydrogen, a substituted or non-substituted alkyl group, or a substituted or non-substituted aromatic group, Y is hydrogen or cyano group, it can be involved the case that one of Ys may be hydrogen and the other may be cyano group, and n is an integer of 1 to 3. The derivative is used for forming films.
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
