Title:
HIGH MOLECULAR COMPOUND, METHOD FOR PRODUCING SAME, AND LIGHT-EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/073903
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a high molecular polymer from which sufficient luminance can be obtained even at a low drive voltage in a case in which the high molecular polymer is used in a light-emitting element. A high molecular compound in a preferred embodiment comprises a block (A) including a plurality of first groups and also including a structure in which the first groups are linked to each other by a second group represented by formula (0-0). The high molecular polymer has at least the groups represented by formula (0-1) or formula (0-2) as the first groups. (In the formula, Ar0 represents an optionally substituted arylene group or divalent aromatic heterocyclic group, which is a group having a structure different from the first groups; n represents the average chain length of Ar0, and is a number from 1.0 to 8.0; and X11 to X16 and X21 to X25 in formula (0-1) and formula (0-2) represent carbon atoms or nitrogen atoms, where two or three among X11 to X16 are nitrogen atoms, and three among X21 to X25 are nitrogen atoms.)
