HETERO COMPOUNDS AND ORGANIC LIGHT EMITTING DEVICES COMPRISING THE SAME

摘要

The present invention relates to a hetero compound represented by chemical formula 1. In chemical formula 1, each of R_1 and R_2 independently represent any one selected from H and a substituted or non-substituted C3-C30 heteroarylene group with the proviso that at least one of R_1 and R_2 is a heteroarylene group; L is a substituted or non-substituted C6-C30 arylene group or substituted or non-substituted heteroarylene group; each of R_3 and R_4 independently represent any one selected from H, a substituted or non-substituted C6-C30 arylene group, C1-C10 alkyl group and C3-C30 heteroarylene group; and at least one of the two dotted lines is bound.
