Abstract
A 1-substituted 2,5-dithienylpyrrole derivative having the following 1 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.
