CROSS-LINKABLE POLYMER, CROSS-LINKED MATERIAL OF THE CROSS-LINKABLE POLYMER, ORGANIC LIGHT EMITTING DIODE COMPRISING THE CROSS-LINKED MATERIAL AND METHOD FOR PREPARING THE ORGANIC LIGHT EMITTING DIODE

摘要

PURPOSE: A cross-linkable polymer is provided to enable the crosslinking by a cross-linkable moiety and to improve the efficiency, electric current density, and brightness of an organic light-emitting device. CONSTITUTION: A cross-linkable polymer is represented by chemical formula 1. The crosslinking group is selected from the group consisting of a C1-C30 alkyl group, C1-C30 alkoxy group, C6-C30 aryl group, C6-C30 aryloxy group, and C3-C30 heteroaryl group, including one or more cross-linkable moieties. The average molecular weight of cross-linkable polymer is 2,000-1,000,000. An organic light-emitting device includes a substrate, a first electrode, a second electrode, and a first layer which is interposed between the first and second electrodes and includes the cross-linked material of the cross-linkable polymer.
