Process for producing a membrane which is intended to be attached to an electrochemical sensor, by polymerizing a starting mixture of prepolymer and initiator in a thin layer on a substrate or by solvent casting a previously prepared polymer solution as a starting mixture in a thin layer a substrate, characterized in that a compound of the following general formula is added to the membrane in the starting mixture to form ionic sites: wherein X is boron, aluminum, nitrogen, phosphorus, arsenic or antimony; R is alkyl, aryl, haloalkyl or haloaryl; Y is a group with the following general formula: Here R 1 is hydrogen, alkyl, aryl or halogen and R 2 : - (CH 2 ) n -O-CH 2 ; where n ≥ 0; or Y is a group with one of the following formulas: -R 3 -OH; -R 3 -SH; -R 3 R 4 -NH; -R 3 -sugar: -R 3 -protein; -R 3 -NCO; or -R 3 -NCS, wherein R 3 is alkyl, aryl or alkylaryl; and... |
