Outline of Final Research Achievements

Concentration of oxygen gas under nitrogen, argon atmosphere, and vacuum are much less than that under air. We have synthesized dye based on material where Cu(I) ion are connected to fluorinated diphosphine at the molecular level. Under dark conditon, we could not see the solid, but under UV light the solid looks blue. This is emission (photoluminescence) phenomenon. The solid looks bright blue under low oxygen ratio. On the other hand, the solid is invisible under high oxygen ratio. We call this emission as oxygen visualizable emission in the solid state. We have synthesized solid which shows this rare phenomena, and increased colour valiation.
