<p>An oxygen sensitive polymeric material with enhanced photostability, comp rising an oxygen sensitive indicator and photostabilizer incorporated into a n oxygen permeable polymeric material is provided. The oxygen sensitive indi cator can be, but is not limited to, [Ru(L1)(L2)(L3)]2+, wherein Ru represen ts the central ruthenium ion, L1, L2 and L3 represent the bidentate ligands diphenylphenanthroline, phenanthroline or bipyridine ligands or optionally s ubstituted variations of same with representative counter ions selected from (PF6)-, Cl-, BF4-, Br- and (C 104)-, platinum or palladium based metallo- p orphyrin. The photostabilizer is selected from CIBA TINUVIN 5236, TINUVIN 29 2, TINUVIN 123 and TINUVIN 272, TINUVIN 477W, DABCO and ascorbic acid. A sen sor system for detecting oxygen and a method for detecting oxygen in a packa ge is also provided.</p> |
