Abstract:
A conjugated polymer comprising repeating units of the formula (I), ##STR1## where the symbols and indices have the following meanings: .PSI. is an element of the 4th main group of the Periodic Table with the exception of carbon;D, E, F, G are identical or different and are --CR.sup.1 R.sup.2 --, --O--, --S--, --NR.sup.3 -- or a chemical bond;U is --CR.sup.4 .dbd.CR.sup.5 -- or a chemical bond;V is as defined for U or is --CR.sup.1 R.sup.2 --, --O--, --S--, --NR.sup.3 --, --SiR.sup.1 R.sup.2 --, --SO.sub.2 --, --O--, --CO--;A are identical or different and are H, a C.sub.1 --C.sub.20 -hydrocarbon radical which can also contain heteroatoms;T is --O--, --S--, --NR.sup.3 --, --CR.sup.1 R.sup.2 --, --CH.dbd.N--, --CA.dbd.CA--, --CH.dbd.CA--, --CH.dbd.CF-- or --CF.dbd.CF--;K, Q are identical or different hydrocarbon radicals which can contain heteroatoms and have conjugated electron systems;M, L are H or a straight-chain or branched alkyl group having from 1 to 22 carbon atoms, Br, Cl, F, CN, NO.sub.2 or CF.sub.3 ;m, n are identical or different and are 0, 1, 2, 3 or 4; and wherein said polymer is suitable as an electroluminescence material.
