POLYMER COMPOUND AND POLYMER LIGHT-EMITTING DEVICE

摘要

Disclosed is a polymer compound having a conjugated polymer main chain and a side chain selected from the following (a)-(c). (a) A side chain having an electron transport property. The value of the LUMO energy of this side chain is different from that of the LUMO energy of the conjugated polymer main chain, and the absolute value of the difference is 0.3 eV or less. (b) A side chain having a hole transport property. The value of the HOMO energy of this side chain is different from that of the HOMO energy of the conjugated polymer main chain, and the absolute value of the difference is 0.3 eV or less. (c) A side chain having an electron transport property and a hole transport property. The value of the LUMO energy of this side chain is different from that of the LUMO energy of the conjugated polymer main chain, and the absolute value of the difference is 0.3 eV or less. The value of the HOMO energy of this side chain is different from that of the HOMO energy of the conjugated polymer main chain, and the absolute value of the difference is 0.3 eV or less.
