The present invention relates to a supported chemical compound of the formula (I) (see fig. I) in which Ac+ is a cation, c is an integer from 1 to 10, b is an integer ~0, T is a support, y is an integer ~1, a is an integer from 0 to 10, where a~y = c~b, and N is a unit of the formula (II) (see fig. II) in which R independently at each occurrence is an identical or different substituent of M, such as a halogen atom or a C1-C40 carbon-containing group, such as a C1-C40-alkyl, C1-C40-haloalkyl, C6-C40-aryl, C6-C40-haloaryl, C7-C40-arylalkyl or C7-C40-halo-arylalkyl group, X independently at each occurrence is identical or different and is a C1-C40 carbon-containing group, for example a divalent, carbon-containing group such as a C1-C40-alkylene, C1-C40-haloalkylene, C6-C40-arylene, C6-C40-haloarylene, C7-C40-arylalkylene or C7-C40-halo-arylalkylene, C2-C40-alkynylene, C2-C40-haloalkynylene, C2-C40-alkenylene or C2-C40-haloalkenylene group, or a trivalent, carbon-containing group, such as a C1-C40-alkanetriyl, C1-C40-haloalkanetriyl, C6-C40-arei,el,iyl, C6-C40-haloarenetriyl, C7-C40-arenealkanetriyl, C7-C40-haloarenealkanetriyl, C2-C40-alkynetriyl, C2-C40-haloalkynetriyl, C2-C40-alkenetriyl or C2-C40-haloalkenetriyl group, M independently at each occurrence is identical or different and is an element of group lla, Illa, IVa or Va of the Periodic Table of the Elements, d is 0 or 1, e is 0 or 1, f is 0 or 1, g is an integer from 0 to 10, h is an integer from 0 to 10, k is an integer from 0 to 10, r is an integer from 0 to 10, is an integer from 0 to 1000, is an integer from 1 to 6, S at each occurrence is identical or different and is a spacer which links M covalently with T, w is identical or different at each occurrence and is 0, 1 or 2, and z is 0, 1 or 2.
