Luminescent ionic liquids based on cyclometalated platinum(ii) complexes exhibiting thermochromic behaviour in different colour regions†
Abstract
Luminescent ionic liquids, based on anionic Pt(II) complexes, were developed. Depending on the cyclometalating ligands used, they exhibit thermochromic luminescence with different colours. The chromic properties in the flexible liquid and glass states emerge through the self-assembling character of the square-planar Pt(II) complexes.
