A composite material for sensing a chemical species in a medium is provided. The composite material includes a polymer having a glass transition temperature, a porosity promoter dispersed in the polymer in an amount such that the chemical species is transportable from the medium into the composite material at a temperature below the glass transition temperature, and a chemical indicator dispersed in the composite material, the chemical indicator providing an optical response varying with a concentration of the chemical species in the composite material.

A composition comprising a pH indicator, a polymerizable group, and a spacer therebetween. The polymerizable group can be acrylate or methacrylate and the spacer can be an oxyalkayl group, an oxypropyl group, or an oxybenzoyl group. The composition can be polymerized to copolymers to form indicating polymers and optodes.
