Konjugierte Polymere mit Hetero-Spiroatomen und ihre Verwendung als Elektrolumineszenzmaterialien

摘要

A conjugated polymer containing recurrent unit of the formula (I) in which PSI is an element of the 4th main group of the periodic system except for carbon; D, E, F<1>, G are the same or different, and mean -CR<1>R<2>-, -O-, -S-, -NR<3>- or a chemical bond; U<1> is -CR<4>=CR<5>- or a chemical bond; V<1> means U or is -CR<1>R<2>-, -O-, -S-, -NR<3>-, -SiR<1>R<2>-, -SO2-, -SO-, -CO-; A is the same or different and means H, a C1-C20 hydrocarbon radical which may also contain a heteroatom; T is -O-, -S-, -NR<3>-, -CR<1>R<2>-, -CH=N-, -CA=CA-, -CH=CA-, -CH=CF- or -CF=CF-; K, Q are the same or different and are hydrocarbon radicals which may contain heteroatoms and are characterised by conjugated electron systems; M, L are H or a straight or branched-chain alkyl group with 1 to 22 C atoms, Br, Cl, F, CN, NO2 or CF3; m, n are the same or different and are 0, 1, 2, 3 or 4; said polymers are suitable as electroluminescent materials.
