Conjugated system-containing organic high molecular compound

摘要

A conjugated system-containing organic high molecular compound is described, which contains a recurring unit represented by the following structural formula (I) and has a number-average molecular weight of 1,000 or more: ##STR1## wherein m represents an integer of from 2 to 10; n represents an integer of from 1 to 23; B and B' respectively represent -- NHCO-- and --CONH--, --CONH-- and --NHCO--, ##STR2## --A-- is selected from the group consisting of ##STR3## wherein R.sup.1-4 and R. sup.5-8 each independently is selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group having 1 to 5 carbon atoms, an amino group, an alkylamino group having 1 to 5 carbon atoms, a hydroxyl group, an alkoxyl group having 1 to 5 carbon atoms, a cyano group, a nitro group, and groups of the following formulae (a), (b), and (c), provided that the groups of --A-- may be the same or different: ##STR4## wherein R.sup. 9-12, R.sup.13-16, and R.sup.17 each independently is selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group having 1 to 5 carbon atoms, an amino group, an alkylamino group having 1 to 5 carbon atoms, a hydroxyl group, an alkoxyl group having 1 to 5 PG,3 carbon atoms, an aldehyde group, a carboxyl group, a cyano group, and a nitro group; and &agr; and &bgr; each independently is selected from the group consisting of a hydrogen atom, a cyano group, and a nitro group.
