Abstract:
A monomeric, oligomeric or polymeric compound comprising one or more identical or different recurring units of formula I: whereinD, Dâ€² are independently of each other a group of the following formulae 1 to 3: R1, R2 are independently of each other halogen, straight chain, branched or cyclic alkyl with 1 to 20 C-atoms, which are unsubstituted, mono- or poly-substituted by F, Cl, Br, I, â€”CN and/or â€”OH, and in which one or more non-adjacent CH2 groups are, optionally replaced, in each case independently from one another, by â€”Oâ€”, â€”Sâ€”, â€”NHâ€”, â€”NR0â€”, â€”SiR0R00â€”, â€”COâ€”, â€”COOâ€”, â€”OCOâ€”, â€”OCOâ€”Oâ€”, â€”Sâ€”COâ€”, â€”COâ€”Sâ€”, â€”CH&boxH;CHâ€” or â€”Câ‰¡Câ€” in such a manner that O and/or S atoms are not linked directly to one another, or optionally substituted aryl or heteroaryl, or one of R1 and R2 also H, R0 and R00 are independently of each other H or alkyl with 1 to 12 C-atoms, Ar is a bivalent mono-, bi- or tricyclic aromatic or heteroaromatic group with up to 25 C atoms that may also comprise condensed rings and is optionally mono- or poly-substituted with F, Cl and/or groups R1 as defined above, and a, b are independently of each other 0 or 1.
