Process for preparing co-gels having polyazacycloalkane moieties and their use

摘要

Polyazamacrocyclic compounds of formula (I) are new. Compounds of formula (I) are new: W1, W2 and W3 (same or different) each = a divalent radical of formula (II): -((CT1T2)n-(N(R4))p-(CT3T4)m)l- (II); p = 0 or 1; l = 1 or 2; n and m (same or different) each = 1, 2 or 3; T1, T2, T3 and T4 (same or different) either each independently = H, 1-15 C linear or branched alkyl or a 7-12 C ((hetero)aryl)alkyl radical, or CT1T2 and/or CT3T4 may = a divalent -(C=O)- group; R4 = H, 1-15 C linear or branched alkyl which is optionally substituted by one or more functional groups, a 7-12 C ((hetero)aryl)alkyl radical or a radical of formula (III): R5-Si(X1)(X2)(X3) (III); X1, X2 and X3 (same or different) each independently = H, halogen or -OR6 in which R6 = H or 1-4 C alkyl; R5 = a divalent radical derived from a 1-10 C saturated or unsaturated aliphatic chain which may be interrupted by one or more structural groups selected from arylene groups, -O-, -S-, -O-C(=O)-, -N(R7)-C(=O)- or -N(R7)- in which R7 = H, 1-6 C aliphatic hydrocarbon radical, benzyl or phenethyl, and the chain optionally being substituted by one or more radicals selected from halogen, OH, 1-4 C alkyl, benzyl or phenethyl; R1, R2 and R3 (same or different) each independently = R4, H, 1-15 C linear or branched alkyl which is optionally substituted by one or more functional groups, or a 7-12 C ((hetero)aryl)alkyl radical, or a radical of formula (III) above; with the proviso that at least one of the ring N atoms is substituted by a radical of formula (III) above.
