OXYGEN-ABSORBING/DESORBING COMPOSITION, REAGENT FOR OXYGEN CONCENTRATION ABSORPTIOMETRY USING THE OXYGEN-ABSORBING/DESORBING COMPOSITION, OXYGEN CONCENTRATION MEASURING METHOD, AND OXYGEN AFFINITY CALCULATION METHOD OF BINUCLEAR COPPER COMPLEX

摘要

PROBLEM TO BE SOLVED: To provide an oxygen absorbing/desorbing composition capable of absorbing/desorbing oxygen at a room temperature, a reagent for oxygen concentration absorptiometry using the oxygen-absorbing/desorbing composition, an oxygen concentration measuring method, and an oxygen affinity calculation method of a binuclear copper complex.;SOLUTION: An oxygen concentration is measured, by using as a reagent the oxygen absorbing/desorbing composition formed by adding a nitryl compound to a solution acquired by dissolving the binuclear copper complex represented by [Cu₂(RCN)₂(H6M4h)](PF₆)₂ (Formula 1) or [Cu₂(RCN)₂(M6M4h)](PF₆)₂ (Formula 2) into an organic solvent, or oxygen affinity of the binuclear copper complex is calculated. In the Formulas (1), (2), R is an alkyl group or a phenyl group, and H6M4h is 1,2-bis[2-(bis(6-methyl-2-pyridyl)methyl)-6-pyridyl]ethane, and M6M4h is 1,2-bis[2-(1,1-bis(6-methyl-2-pyridyl)ethyl)-6-pyridyl]ethane.;COPYRIGHT: (C)2007,JPO&INPIT
