Abstract

Colour-changing chemical sensors have found important applications in the detection of low concentrations of volatile organic compounds (VOCs). Among the most promising molecular materials are platinum pincer complexes that display rapid colour changes when exposed to a variety of VOCs. In the solid state, these rapid responses have been linked to changes in non-covalent interactions between the platinum pincer molecules and the guest VOCs. To gain a better understanding of the interactions involved, we have studied the manipulation of vapochromic or solvatochromic properties in a series of square planar platinum(II) pincer complexes through structural modification of the monodentate ligand occupying the fourth coordination site. The platinum(II) complexes are based on the 1,3-di(pyridine)benzene tridentate linker (N^C^N) skeleton with the fourth site occupied by a monodentate, anionic ligand L.
