Abstract:
A conductive polymer material comprising a polymer having a &pgr;-electron conjugated molecular structure comprising a dopant comprising at least one of aromatic sulfonic acid derivatives represented by general formula 1: wherein at least one of R1 to R6 represents a sulfonic acid group having a counter cation selected from the group consisting of a hydrogen ion, an alkali metal ion, an alkaline-earth ion and a transition metal ion belonging to groups 8 to 10 in the periodic table; and the remaining R1 to R6, which may be the same or different, represent hydrogen, alkyl having four or less carbon atoms or phenyl; or any two or more of R1 to R6 may be combined together to form an aromatic or aliphatic ring; and general formula 2: wherein at least one of R7 to R10 represents a sulfonic acid group having a counter cation selected from the group consisting of a hydrogen ion, an alkali metal ion, an alkaline-earth ion and a transition metal ion belonging to groups 8 to 10 in the periodic table; and the remaining R7 to R12, which may be the same or different, represent hydrogen, alkyl having four or less carbon atoms or phenyl; or any two or more of R7 to R10 may be combined together to form an aromatic or aliphatic ring.
