摘要
Dicyano(4,4'-dicarboxy-2,2'-bipyridine)platinum(II) forms pH-dependent polymorphs of various colors and displays outstanding vapochromism followed by luminescence changes upon exposure to certain organic vapors. The high sensitivity of the complex to vapor and pH is related to its three-dimensional network structure, which includes large cavities formed by hydrogen bonds and Pt center dot center dot center dot Pt interactions.
