Abstract

The planar platinum(II) complex [Pt(Me3SiC[triple bond, length as m-dash]CbpyC[triple bond, length as m-dash]CSiMe3)(C[triple bond, length as m-dash]CC6H4Et-4)2] (1) with 5,5-bis(trimethylsilylethynyl)-2,2′-bipyridine was prepared and characterized. Solid-state 1 exhibits unusual, selective and reversible luminescence vapochromism to CH3CN and ClCH2CN vapors, which is useful for the detection of these hazardous vapors. A vapochromic cycle was monitored by dynamic variations in emission spectra and X-ray diffraction (XRD) patterns. Both X-ray crystallographic and density functional theory studies suggest that the vapochromic and vapoluminescent behavior of 1 are induced by the variation in the intermolecular Pt–Pt interactions.
