Double-decker platinum complexes with N -heteroaromatic ligands have attracted increasing interest due to their outstanding luminescent properties and rich redox behavior. In this review, the design principles and recent observations on luminescent and redox-active double-decker platinum complexes are discussed. Because these properties are precisely controlled by intra- and intermolecular Pt⋯Pt electronic interactions, double-decker platinum complexes have been also used to obtain phenomena driven by stimulus–responsive color and luminescence change, such as vapochromism, mechanochromism, thermochromism, and electrochromism. This review also summarizes chromic materials based on double-decker platinum complexes influenced by changes in the Pt⋯Pt electronic interactions. [ABSTRACT FROM AUTHOR]

An ionic liquid fabricated from an anionic cyclometalated platinum(ii) complex and an imidazolium cation exhibits dual emission from the monomeric and aggregated forms of the platinum complex anions, leading to temperature-dependent color changes of luminescence. [ABSTRACT FROM AUTHOR]

A cyclometalated dinuclear platinum(II) complex bridged with pyridine-2-thiolate ions, [Pt2(ppy)2(pyt)2] (Hppy = 2-phenylpyridine, Hpyt = pyridine-2-thiol) and its oxidized platinum(Ill) complex, [Pt2Cl2(ppy)2(pyt)2] have been synthesized and characterized. The divalent complex exhibits intense red luminescence both in solution and in the solid states. Corresponding to the short Pt ... Pt distance (2.849(1) Å) for [Pt2(ppy)2(pyt)2], the reversible conversion between the divalent and trivalent complexes occurs easily with appearance and disappearance of the luminescence.
