Vapochromic Soft Crystals Constructed with Metal Complexes

Abstract Vapochromism, a phenomenon in which the color or luminescence of substance changes response to gaseous molecules, has potential for developing sensor materials detect harmful substances environment. In addition, vapochromism is scientifically interesting direct visualization interactions between gases and solids. The crystals metal complexes involve diverse flexible electronic interactions, such as metal–metal metal–ligand interactions. It expected that slight structural will lead distinct emission changes, thus achieving highly sensitive selective vapochromic responses. Consequently, ordered systems (i.e., soft crystals) can be constructed. This chapter introduces attractive features vapor-responsive by discussing platinum show dilute vapor atmospheres while maintaining an structure, nickel(II) change magnetic properties conjunction with change, copper(I) N-heteroaromatic vapors.
