| abstract |
A composition comprising a polymer compound containing structural units represented by formula (1), and one or more types of compounds selected from the group consisting of compounds containing Pd, compounds containing P, and compounds containing Pd and P, wherein the content of the polymer compound is at least 95 mass%, the content of Pd is not more than 50 ppm, and the content of P is not more than 60 ppm. (In the formula, the A ring and the B ring independently represent an optionally-substituted C2-30 heterocycle. The C ring represents either an optionally-substituted C6–30 aromatic hydrocarbon ring or an optionally-substituted C2–30 heterocycle. Z1 represents a group represented by formula (Z-1), a group represented by formula (Z-2), a group represented by formula (Z-3), a group represented by formula (Z-4), or a group represented by formula (Z-5). The plurality of Z1 which are present may be the same or different. In the formula, R1 represents an optionally-substituted C1–30 alkyl group, an optionally-substituted C3–30 cycloalkyl group, or the like. If a plurality of R1 groups are present, said groups may be the same or different.) |
