Nafion-lnduced Metal-Metal Interactions in a Platinum（Ⅱ） Terpyridyl Acetylide Complex： a Luminescent Sensor for Detection of Volatile Organic Compounds

The platinum(Ⅱ) terpyridyl acetylide complex Pt(terpy)(C≡CR)]ClO4 (terpy=2,2‘ : 6‘2“-terpyridine, R=CH2CH2CH3) (1) was incorporated into Nation 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 Nation-supported complex as an interesting sensor candidate for polar VOC.

Nafion‐induced metal‐metal interactions in a platinum(II) terpyridyl acetylide complex: A luminescent sensor for detection of volatile organic compounds

The platinum(II) terpyridyl acetylide complex Pt(terpy)(C?CR)]ClO₄ (terpy=2,2′ : 6′2″‐terpyridine, R=CH₂CH₂CH₃) (1) was incorporated into Nafion membranes.
