New quinoxaline compound, useful in organic solar cells as an exciton blocker or electron transport layer and in organic light-emitting diodes as an electron transport layer or emitter matrix

摘要

Quinoxaline compound (I) is new. Quinoxaline compound of formula (I) is new. M : Ti, Zr, Hf, Nb, Re, Sn or Ge; and R : H, 1-20C-alkyl, 1-20C-alkenyl, 1-20C-alkynyl, aryl, heteroaryl, oligoaryl, oligoheteroaryl, oligoarylheteroaryl, OR x, NR xR y, SR x, NO 2, CHO, COOR x, halo, CN, NC, SCN, OCN, SOR xor SO 2R xor part of a condensed ring system; and R x, R y1-20C-alkyl, 1-20C-alkenyl or 1-20C alkynyl. An independent claim is also included for an organic semiconductor material comprising at least one organic matrix material that is doped with at least one dopant, where the matrix material is a quinoxaline compound (I).
