Abstract

Newly prepared water-soluble iridium phosphorescent complexes, trans-[Ir(ppy)(PAr₃)₂(H)L]^0,+ (ppy = bidentate 2-phenylpyridinato anionic ligand; L= Cl (1), CO (2), CN- (3); H being trans to the nitrogen of ppy ligand; PAr₃ (TPPTS) = P(m-C₆H₄SO₃Na)₃), have been synthesized and characterized. Those complexes containing water-soluble phosphine ligands can emit any color region as altering cyclometalated ligands in aqueous media with high quantum efficiencies. Even though these water-soluble phosphorescent iridium complexes can be the sensing probe for toxic CO gas and CN anion, they will be capable of promising materials in the solution processible OLED applications.
