    • The series of platimun(II) dinuclear complexes were synthesized for new optical oxygen sensing material instead of conventional platinum porphyrins. An optical oxygen-sensing activity of anchored platimun(II) dinuclear complexes on ordered anodic oxidized aluminum film was studied in relevance to development of new oxygen-sensing systems. The luminescence intensity of platinum(II) dinuclear complexes onto anodic oxidized aluminum film decreased with increasing oxygen concentrations. The response time for the change of the atmospheric gas from oxygen to argon in platimun(II) dinuclear complex on ordered anodic oxidized aluminum film was faster than that of the sensor device based on the conventional platinum porphyrins.
