A novel sensitive probe for proton based on platinum(II) terpyridyl acetylide complex by monitoring the changes both in luminescence and color is described.
An acetylide-bridged dinuclear platinum(II) terpyridyl complex, [Pt(4’-p-tolyl-terpy)-≡-phenyl-≡-(4’-p-tolyl- terpy)Pt](ClO4)2 (1), has been successfully synthesized and its photophysical properties are reported.
