Luminescence vapochromic properties of a platinum(ii) complex with 5,5′-bis(trimethylsilylethynyl)-2,2′-bipyridine

Abstract

A platinum(II) complex of 5,5'-bis(trimethylsilylethynyl)-2,2'-bipyridine displays unusually reversible colour and luminescence changes when exposed to specific organic vapours, correlated well with Pt...Pt distances as well as pi-pi and C-H...(C[triple bond]C) interactions in the stacking of square-planar platinum(II) moieties.
