    Abstract: 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 , G are the same or different, and mean -CR R -, -O-, -S-, -NR - or a chemical bond; U is -CR =CR - or a chemical bond; V means U or is -CR R -, -O-, -S-, -NR -, -SiR R -, -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 -, -CR R -, -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.

    Abstract: Amphiphilic monomers with mixed-chain structures of the formula in which Y denotes -O- or -NH- X denotes a group of the formula -(CH2)n- or -(CH2-O-CH2)n- l denotes an integer from 0 to 10, n denotes an integer from 1 to 10, R1 denotes hydrogen, methyl, chlorine, cyano, fluorine or bromine, R2 denotes C1-C24-alkyl or C1-C24-fluoroalkyl and R3 denotes C8-C24-alkyl or C8-C24-fluoralkyl, with the proviso that the groups R2 and R3 contain a different number of carbon atoms. The monomers are polymerized on their own or together with other comonomers. The polymers obtained are suitable for the preparation of ultra-thin layers on a suitable layer support.

    Abstract: New polyamide (I) contg. medium to long-chain alkyl gps. is of the formula: -(N(A) X N(B) CO Y CO)n (I); (where Y = a divalent gp.; X = a divalent gp. with at least 2C atoms in the chain; A and B independently = H or 1-26C alkyl; n = over 4). (I) contains at least o ne 6-26, esp. 14-20C alkyl gp./recurring unit. The novelty is that X and/or Y contain at least one CH2 gp. in the chain.

    Abstract: The use of spiro cpds. of formula (I) or of conjugated polymers (II) contg. recurring units of formula (IIA) in non-linear optical applications is claimed; psi = C, Si, Ge or Sn, pref. (I) psi = Ge, esp. Si or more esp. C; K , K = conjugated systems; D, E, F, G = -CR R -, -O-, -S-, -NR - or a chemical bond; R , R , R = 1-20 C alkyl or H; or R + R form an opt. substd. cycloalkyl ring; U = -CR =CR - or a chemical bond; V = U, -CR R -, -O-, -S-, -NR -, -SiR R -, -SO2-, -SO- or -CO-; R , R = as R or F or CF3; A = H or 1-20 C hydrocarbyl, opt. contg. hetero-atom(s); R , R = H, 1-20 C aliphatic, alicyclic or aromatic hydrocarbyl or R + R form a ring; T = -O-, -S-, -NR -, -CR R -, -CH=N-, -CA=CA-, -CH=CA-, -CH=CF- or -CF=CF-; K, L, M, Q = hydrocarbyl gps., opt. contg. hetero-atom(s), with conjugated electron systems, which may form a satd. or partly or max. unsatd. ring with the A gp. in the ortho-position, esp. an annelated aromatic ring system; L, M may also = H, unconjugated hydrocarbyl (pref. with 1-20 C atoms and opt. hetero-atom(s)), halogen, CN, NO2, NH2 or (di)alkylamino; m, n = 0, 1, 2 or 3.
