An optochemical sensor for determining a pH of a measured medium includes a sensor membrane having an analyte-sensitive layer. The sensor membrane has a first luminophoric dye in the form of an indicator dye and a second luminophoric dye in the form or a reference dye. At least one of the two aforementioned dyes is contained in the analyte-sensitive layer, and one of the two aforementioned dyes has an inorganic framework structure. At least one inorganic or organic receptor group, which is protolyzable, is bonded to the framework structure.
