Polymer compound, net-like polymer compound produced by crosslinking the polymer compound, composition for organic electroluminescence element, organic electroluminescence element, organic EL display, and organic EL lighting

摘要

An object of the invention is to provide a polymer compound having a high hole transport capacity, excellent in electrochemical stability, and suitable to film formation according to a wet film formation method. Another object of the invention is to provide an organic electroluminescence element having a high current efficiency, a low drive voltage, and a long derive lifetime. The polymer compound has a crosslinking group bonding to the arylamine moiety in the repeating unit via at least one single bond therebetween.
