POLYMER AND SOLAR CELL USING THE SAME

摘要

In one embodiment, a polymer includes a recurring unit containing a bivalent group expressed by a formula (1) shown below. A weight-average molecular weight of the polymer is in a range of 3000 or more to 1000000 or less.;;R1 is a monovalent group selected from hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkanoyl group, a substituted or unsubstituted awl group, and a substituted or unsubstituted heteroaryl group. X is an atom selected from oxygen, sulfur, and selenium. Y and Z are each independently a bivalent group selected from a carbonyl group, a sulfinyl group, and a sulfonyl group. A case where Y and Z are both the carbonyl groups is excluded.

1. A polymer comprising a recurring unit containing a bivalent group expressed by the following formula (1), wherein R1 group is a monovalent group selected from the group consisting of hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkanoyl group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaryl group, X is an atom selected from the group consisting of oxygen, sulfur, and selenium, and Y and Z are each independently a bivalent group selected from the group consisting of a carbonyl group, a sulfinyl group, and a sulfonyl group, with a case where Y and Z are both the carbonyl groups being excluded, wherein a weight-average molecular weight of the polymer is within a range of not less than 3000 nor more than 1000000.
