<p>PURPOSE: Provided are a polymer which can be used as a light-emitting material, a charge transporting material, etc., and a polymer light-emitting device using the polymer. CONSTITUTION: The polymer has a polystyrene reduced number average molecular weights of 10¬3-10¬8, and includes a repeating unit represented by formula (1), in which A¬1is a divalent group represented by -Z- or -Z-Z-, in which Z is an atomic group which may have a substituent; A¬1 represents a divalent group in which the bond distance ratio (bond distance C2-A¬1/bond distance C2-C1) is 1.10 or more, in which C2 is the carbon of alpha position, and C1 is the carbon of (beta) position, respectively to A¬1; R¬1, R¬2, R¬3, R¬4, R¬5, and R¬6, each independently represent a hydrogen atom, a halogen atom, an alkyl group, alkenyl group, alkynyl group, alkyloxy group, alkylthio group, an alkylamino group, aryl group, aryloxy group, arylthio group, arylamino group, arylalkyl group, arylalkyloxy group, aryl alkylthio group, arylalkylamino group, substituted silyl group, acyl group, acyloxy group, imino group, amide group, arylalkenyl group, arylalkynyl group, monovalent heterocyclic group, or cyano group; R¬2 and R¬3 may be connected to form a ring; and R¬4 and R¬5 may be connected to form a ring. The atom in the atomic group Z includes Si, P, S, Ge, Sn, Se, or Te.</p> |
