摘要：
Conjugated polymers comprising recurring 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 each, for example, --O-- or a chemical bond; U is, for example, a chemical bond; V is, for example, as defined for U or is --O--; A are identical or different and are each, for example, H or a C.sub.1 -C.sub.20 -hydrocarbon radical; T is, for example, --O-- or --CA.dbd.CA--, where A is as defined above; K, L, M, Q are identical or different and are hydrocarbon radicals which can contain heteroatoms and have conjugated electron systems; m, n are identical or different and are 0, 1, 2, 3 or 4; are suitable as electroluminescence materials.
