Abstract:
1. A polymer compound having a polystyrene reduced number average-molecular weight of 10 3 -10 8 , and comprising at least one repeating unit resented by formula (1), wherein Ar 1 , Ar 2 , Ar 3 and Ar 4 each independently represent an arylene group or a divalent heterocyclic group; E 1 , E 2 , and E 3 each independently represent the below aryl group (A); a and b each independently represent 0 or 1, and a+b=1, aryl group (A): an aryl group which has three or more substituents selected from an alkyl group, an alkoxy group, an alkylthio group, an aryl group, an aryloxy group, an arylthio group, a substituted amino group, a substituted silyl group, a substituted silyloxy group, or a monovalent heterocyclic group, wherein the aryl group (A) has substituents on the carbon atoms selected by following (C), (C): An arylamine compound derived from aryl group (A) by replacing the free bond of aryl group (A) with amino group, and by replacing all the substituents of aryl group (A) with hydrogen atoms, is considered for the calculation; the highest occupied molecular orbital (HOMO) of the arylamine compound calculated by AM1 method which is a semi-empirical molecular orbital method, is selected; sum square values of atomic orbital coefficients of the HOMO are calculated only about the carbon atoms to which a hydrogen atom is bonded, and three or more carbon atoms are selected from the carbon atoms having large sum square value in descending order.
