    Abstract

    This paper describes a new method for the immobilisation of metalloporphyrin molecules for optical oxygen sensing. The porphyrin molecules have an acrylamide group attached allowing the porphyrin indicator to be covalently bound within a hydrogel polymer. Two hydrogel monomers: hydroxyethyhnethylacrylamide (HEMA) and acrylamide have been investigated to assess their suitability as host polymers for the porphyrins. The photophysics of both the base (non-metal) and Platinum porphyrin: tetra (2- acrylamide phenyl) porphyrin are discussed. Platinum tetra (2-acrylamide phenyl) porphyrin bound in a hydrogel polymer using hydroxyethyl methacrylate (HEMA) as the monomer unit was found to have a good sensitivity to oxygen.
