Recently, vapochromic materials have drawn increasing attention because of their promising vapor sensing functions. In this paper, from the viewpoint of structural chemistry, several types of vapochromic metal complexes are described. The first one is vapochromic materials composed of Pt (II)-diimine complexes in which the origin of vapochromic behavior is the modification of the intermolecular metallophilic interactions. Second are the materials utilizing porous frameworks to adsorb/desorb vapor molecules. Third is the vapochromic hydrogen-bonded proton-transfer assembly which can recognize the hydrogen-bonding ability of vapor molecules.
