摘要：

Polymethacrylate containing perfluoro-group, poly(isobutylmethacrylate-co-trifluoroethylmethacrylate) is synthesized and applied to the matrix of optical oxygen sensing using platinum octaethylporphyrin (PtOEP). Optical oxygen sensors based on phosphorescence quenching of PtOEP-polymer (polystyrene, silicone rubber, etc.) by oxygen are developed. Fluoro-polymer film allows large permeability of oxygen. C-F bond length is short; bonding energy is large compared with C-H and electronegativity of fluorine is large, and thus polymers containing perfluoro-groups are stable forward photo-oxidation.
