Abstract
AbstractThe platinum(II) terpyridyl acetylide complex [Pt(terpy)(CCR)]ClO4 (terpy=2,2′ : 6′2″‐terpyridine, R=CH2CH2CH3) (1) was incorporated into Nafion membranes. At high loading the dry membranes exhibit intense photoluminescence with λmax at 707 nm from the 3MMLCT state. which was not observed in fluid solution. Upon exposure to the vapor of polar volatile organic compounds (VOC), this photoluminescence was significantly red‐shifed. This process was fully reversible when the VOC‐incorporated membrane was dried in air. The dramatic and reversible changes in the emission spectra made the Nafion‐supported complex as an interesting sensor candidate for polar VOC.
