Title:

POLYMER AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2017/131190

Kind Code:

A1

Abstract:

Provided is a polymer which contains a polycyclic aromatic compound as a repeating unit and in which the polycyclic aromatic compound contained as a repeating unit is bonded to an adjacent polycyclic aromatic compound that is a repeating unit in such a way as to share one bond that constitutes a benzene ring in the polycyclic aromatic compound. The polymer is obtained through (co)polymerization of a polycyclic aromatic compound having a K region and a silole skeleton as a raw material or a polycyclic aromatic compound having a K region and a polycyclic aromatic compound having a silole skeleton as raw materials, is obtained using a method which has fewer steps and in which secondary reactions are suppressed, and can constitute a GNR in which the width and length are controlled. The repeating unit is preferably a repeating unit represented by general formula (1) [In the formula, * denotes the repeating unit site. m denotes an integer of 1 or higher. A denotes an aromatic ring having a K region. In cases where m is 2 or higher, the plurality of A moieties may be the same as, or different from, each other. R1 and R3 each denote a hydrogen atom. R2 and R4 may be the same as, or different from, each other, and each denote a branched chain alkyl group or a group represented by general formula (2) (In the formula, *, m, A, R1 and R3 are as described above. R2a denotes a branched chain alkyl group. At least one combination of R1 and R2a, R1 and A, and R3 and A may bond to each other to form a ring.) At least one combination of R1 and R2, R3 and R4, R1 and A, and R3 and A may bond to each other to form a ring.]
