Abstract
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.
