Abstract
<p>Photofunctional chromic metal complexes that exhibit remarkable luminescence and color changes in response to gentle stimuli such as chemical vapor and mechanical stimulus have been extensively developed. In particular, squareplanar Pt(II) complex systems that exhibit assembly-induced emission based on the Pt···Pt electronic interactions are significant for vapochromic materials with high sensitivity. The crystal engineering using various intermolecular interactions as well as ligand design realized photofunctional chromic complexes with intense luminescence and/or selective chromic behaviors. In addition to Pt(II) complexes, vapoluminescent Cu(I) complexes were also developed using their labile properties. Selective vapor response accompanied by the remarkable color change coupled with spinstate change was found for a Ni(II) complex bearing a quinonoid ligand. Based on these achievements, a new scientific area regarding flexible response systems with high structural order is developing covering various molecular crystalline materials called soft crystals.</p>
