ポリマーおよび有機エレクトロニクスデバイス
Document Type and Number:
Japanese Patent JP6266962
Kind Code:
B2
Abstract:
A polymer comprising repeat units of formula (I) and one or more co-repeat units:
Ar 1 in each occurrence independently represent an aryl or heteroaryl group;
R 1 and R 2 in each occurrence independently represent a substituent;
p independently in each occurrence is 0 or a positive integer;
Sp represents a spacer group comprising at least one carbon or silicon atom spacing the two groups Ar 1 apart; and
each group Ar 1 is bound to an aromatic group of a co-repeat unit. The polymer may form a charge-transporting layer of an OLED or may be a host material used with a luminescent dopant in a light-emitting layer of an OLED.
