The invention relates to new compounds of Formula (1): wherein Q is selected from CXYR' and RC(Z) wherein Z is selected from oxygen, hydrogen, OH, NR2 and NNR2R3, and wherein X and Y are each selected from hydrogen, RC(Z), CN or C(O)W and W is selected from OH, OR6, O(M+'')1/'' and NR2R3 and R, R', R2, R3 and R6 are each selected from hydrogen, an optionally substituted linear or branched group selected from C1-40-alkyl, C2-40-alkenyl, C2-40-alkynyl group, an aryl and C1-40-alkylaryl group and M is a metal ion derived from a lanthanide, actinide, main group or transition metal and V is selected from an optionally substituted linear or branched group selected from C1-40-alkyl, C2-40-alkenyl, C2-40-alkynyl group, an aryl group, a C1-40-alkylaryl, sulfide, sulfoxide, sulfone, amine, a polyalkyl amine, a phosphine or other phosphorous containing group; and n is an integer from I to 4. The free valences of the silicate oxygen atoms are saturated by one or more of silicon atoms of other groups of Formula 1, hydrogen, a linear or branched C1-12-alkyl group or by end groups R43M'01/2, cross-linking bridge members or by polymer chains of R4gM'(OR)mOw2 or Al(OR5)3-POP/2 or R4AI(OR5)2_,0,/2; where M is Si or Ti; R5 is a linear or branched C1-12-alkyl group or an aryl or C1-40-alkylaryl group; and R4 is a linear or branched C1-12-alkyl group or an aryl or C1-40-alkylaryl group; k is an integer from I to 3 and q and m are integers from 0 to 2; such that m+k+q=4; p is an integer from I to 3; and r is an integer from 1 to 2. The compounds are useful as scavengers for the removal of unwanted organic and inorganic compounds, for solid phase extraction, for solid phase synthesis, for the immobilisation of bio-molecules, as ion exchanger materials, as catalysts and catalyst supports and as chromatography materials.
