The invention concerns a novel surface-functionalized carrier material with a polymeric surface and at least one linker compound according to the general formula (I), which is covalently bound to the surface. In the formula, P indicates the polymeric surface; R.sup.2 has the meaning OR.sup.4 or NR.sup.4R.sup.5 and R.sup.1, R.sup.4 and R.sup.5, independently of one another, indicate H, an alkyl group or an aryl group; R.sup.3 indicates H, an alkyl, an aryl, an acyl, an alkoxycarbonyl or an aryloxycarbonyl group; and the alkyl, aryl, acyl, alkoxycarbonyl and/or aryloxycarbonyl group of the radicals R.sup.1, R.sup.3, R.sup.4 and R.sup.5, independently of one another, are substituted or unsubstituted. The material according to the invention can be very easily produced by photochemical coupling and serves for the solid-phase synthesis of amino acids, peptides, proteins or molecules with at least one peptidic structural unit.
