New pyrido(3,2-h)quinazoline compounds useful to prepare doped organic semi-conductor, which is useful in an organic light-emitting diode, preferably organic solar cells, and modules for an electronic circuits, preferably displays

摘要

Pyrido[3,2-h]quinazoline compounds (I) and/or their 5,6-dihydro derivatives, are new. Pyrido[3,2-h]quinazoline compounds of formula (I) and/or their 5,6-dihydro derivatives, are new. R 1, R 2 : optionally substituted (hetero)aryl, alkyl of formula (CH(R) 2); R : 1-20C-alkyl or alkyl of formula C(R) 3; R 3 : H, optionally substituted 1-20C-alkyl or (hetero)aryl; and R 4 : H, optionally substituted 1-20C-alkyl, (hetero)aryl, NH 2, NHR, N(R) 2, N-alkylaryl, N-(aryl) 2, carbazolyl, dibenzazepinyl or CN. Independent claims are included for: (1) the preparation of (I); (2) a doped organic semi-conductor comprising at least an organic matrix material doped with at least a dopant, where the matrix material is (I); and (3) a benzylidene dihydroquinoline compound of formula (V).
