Blends comprising conjugated carbazole polymers, synthesis and usage thereof

摘要

Polymers (I) comprise 1-100 mol.% of carbazole units. Polymers (I) comprise 1-100 mol.% of carbazole units of formula (1). [Structure I, p27] (1) R : 3-40C cycloalkyl, 2-40C (hetero)aromatic or 1-16C alkylene-aryl, alkylene-cycloalkyl or alkylene-heteroaryl system all optionally substituted by R 1 with the (hetero)aryl systems optionally part of a larger condensable aromatic ring system; Aryl : 2-40C (hetero)aromatic, stilbenylene and/or tolanylene unit optionally substituted by R 1; R 11-22C optionally cyclic alkyl or alkoxy whereby non-neighboring C atoms are replaced by N-R 2, O, S, -CO-O-, or O-CO-O and at least one H atom is optionally replaced by F, 5-40C aryl or aryloxy with at least one C atom optionally replaced by O, S or N and substituted by a nonaromatic R 1 or Cl, F, CN, N(R 2) 2, B(R 2) 2 whereby two or more R 1 optionally form a ring system; Ra : 1-22C optionally cyclic alkyl or alkoxy whereby non-neighboring C atoms are replaced by N-R 2, O, S, -CO-O-, or O-CO-O and at least one H atom is optionally replaced by F, 5-40C aryl or aryloxy with at least one C atom optionally replaced by O, S or N and substituted by a nonaromatic R 1 or Cl, F, CN, N(R 2) 2, B(R 2) 2; Rb : 1-22C optionally cyclic alkyl or alkoxy whereby non-neighboring C atoms are replaced by N-R 2, O, S, -CO-O-, or O-CO-O and at least one H atom is optionally replaced by F, 5-40 C aryl or aryloxy with at least one C atom optionally replaced by O, S or N and substituted by a nonaromatic R 1 or Cl, F, CN, N(R 2) 2, B(R 2) 2 whereby two or more Rb optionally form a ring system; R 21-22C optionally cyclic alkyl whereby non-neighboring C atoms are optionally replaced by O, S, -CO-O-, O-CO-O and at least one H atom is optionally replaced by F, 5-40C aryl optionally having at least one C atom replaced by O, S or N and optionally substituted by at least one non-aromatic R 1; m : 0-2; o : 0-2 with the proviso that o is not 0 when m is 2; r : 0 or 1; z : 0-3 Independent claims are included for: (1) mixtures comprising polymers (I) with conjugated or non-conjugated polymers and; (2) electronic components, preferably light-emitting diodes comprising at least one active layer containing polymers (I).
