“…For example, Zhang et al reported the unique chiroptical switching behavior of Pt II complexes with chiral pinene containing C ^ N ^ N ligands. [5b] This study demonstrated that the chirality of Pt II complexes can be manipulated by achiral vapor‐induced structural transformation. Another noteworthy work on chiral vapor detection was reported by Mann et al They synthesized a chiral Pt II double salt composed of [Pt(CN) 4 ] 2– and Pt II tetrakis‐ R ‐β‐methylphenethylisocyanide that exhibited different vapochromic responses toward R ‐ and S ‐2‐BuOH vapors.…”

“…Another noteworthy work on chiral vapor detection was reported by Mann et al They synthesized a chiral Pt II double salt composed of [Pt(CN) 4 ] 2– and Pt II tetrakis‐ R ‐β‐methylphenethylisocyanide that exhibited different vapochromic responses toward R ‐ and S ‐2‐BuOH vapors. [5a] These pioneering works clearly indicate that vapochromic Pt II complexes can be utilized for simple vapor detection as well as for chiral manipulation and/or recognition of chiral moieties. However, the effect of the chiral and racemic crystal structural differences on the vapochromic behavior of the Pt II system is still unclear.…”

“…Although most vapochromic Pt II complexes are composed of achiral molecules,, a few pioneering works on chiral Pt II complexes have reported their chirality‐dependent behavior . For example, Zhang et al reported the unique chiroptical switching behavior of Pt II complexes with chiral pinene containing C ^ N ^ N ligands.…”

New luminescent PtII complexes with the chiral counter anions [PtCl(tpy)](l‐Hta) (1‐L) and [PtCl(tpy)](dl‐Hta) (1‐DL; tpy = 2,2′:6′,2′′‐terpyridine; l‐H2ta = l‐tartaric acid; dl‐H2ta = racemic tartaric acid) were synthesized and their vapochromic behavior was evaluated. Single crystal X‐ray analysis revealed that the stacked square‐planar PtII molecules in anhydrous 1‐DL formed a one‐dimensional columnar structure with weak intermolecular Pt···Pt interactions, while in anhydrous 1‐L the PtII molecules were dimerized with Pt···Pt interactions to form a zig‐zag stacked column. These differences were attributed to the different hydrogen bonding in the dl‐ and l‐Hta– ions. The dihydrates of 1‐DL and 1‐L displayed near‐identical crystal structures with comparable emission spectra derived from 3π–π* ligand emission. Both dihydrates exhibited MeOH‐vapor‐induced dehydration to form the anhydrous complexes. These presented broad 3MMLCT emission (549 and 565 nm, respectively), affected by the degree of intermolecular Pt···Pt interactions.

“…The apparatus used to collect the vapoluminescent emission data is similar to that of a previously described previously system. 8 The excitation source is a commercially available LED (Radio Shack) controlled using a variable voltage power supply. Though the light from the LED has a narrow wavelength range, an interference filter was used narrow the excitation profile to ≅5 nm.…”

A convenient synthetic scheme was developed to access a series of square-planar Pt(II) complexes of the form (TBA)[Pt(CN)3(CNR)] (TBA = tetra-n-butyl ammonium cation, R = CH3, c-C6H11, p-(C2H5)-C6H4). These heteroleptic complexes were characterized by combustion analyses, single-crystal X-ray structure determinations, HRFAB-MS, (1)H NMR, ATR-IR, solution UV-Vis, and solid-state emission spectroscopies. Surprisingly, each of these complexes exhibit low energy room temperature solid-state luminescence in the absence of intermolecular Pt-Pt interactions. Additionally, the polymorphic behavior of (TBA)[Pt(CN)3(CN-c-C6H11)] was elucidated through a combination of single-crystal X-ray structure determinations, X-ray powder diffraction, and mass uptake experiments. Vapoluminescence and polymorphic transformations of (TBA)[Pt(CN)3(CN-c-C6H11)] were concomitant with water vapor absorption. A new double-salt complex [Pt(terpy)Cl] [Pt(CN)3(CNCH3)] (terpy = 2,2',6',2''-terpyridine) was also synthesized and characterized by combustion analysis, ATR-IR, HRFAB-MS, and solid-state UV-Vis and emission spectroscopies. The vapoluminescent properties of this salt in response to water were examined by mass uptake experiments, ATR-IR, and solid-state emission spectroscopy. A principal component analysis (PCA) of the solid-state emission changes induced by water vapor confirmed the presence of an intermediate emissive species.

“…Similar to dicyanoaurate‐containing materials, compounds incorporating tetracyanoplatinate have been studied for luminescence‐based detection of a range of analytes . Since the zinc(II) node is clearly an effective, reversible binding site for ammonia in Zn[Au(CN) 2 ] 2 , substitution of the [Au(CN) 2 ] − linker for the similar [Pt(CN) 4 ] 2− was targeted in order to alter the luminescent properties, while retaining the reactivity of the material toward ammonia.…”

ZnPt(CN)4 was shown to be an effective material for ammonia sensing, and can be synthesized using either solution or mechanochemical methods. A combination of luminescence and Raman spectroscopy revealed that multiple species are involved in the reaction between ammonia and ZnPt(CN)4. The crystal structure of one of these species, Zn(NH3)2Zn(NH3)3(Pt(CN)4)2, was elucidated. Detection of ammonia vapor down to 50 ppm in air was accomplished by monitoring the luminescence spectrum. The reaction between ZnPt(CN)4 and ammonia vapor is reversible, and can be cycled multiple times by either flowing air over the material or heating. ZnPt(CN)4 also has a relatively high thermal stability, decomposing only when heated above 420 °C.
