“…Chen and co‐workers also reported an interesting vapochromic Pt II complex, [Pt(Me 3 SiC≡CbpyC≡CSiMe 3 )(C≡Cbpy) 2 ] ( 12 ; Figure 15, left) composed of two kinds of rigid ligands [Me 3 SiC≡CbpyC≡CSiMe 3 = 5,5‐bis(trimethylsilylethynyl)‐2,2′‐bipyridine, HC≡Cbpy = 5‐ethynyl‐2,2′‐bipyridine] 43. X‐ray crystallographic analysis for the chloroform and water co‐adsorbed form 12· 1.5CHCl 3 · 0.5H 2 O indicated that the Pt ··· Pt metallophilic interaction was effective within the dimer [Pt ··· Pt distance = 3.2363(15) Å; Figure 16, left], whereas the Pt ··· Pt distance beyond 4.0 Å in the antiparallel‐packed dimer suggested negligibly weak metallophilic interaction between the Pt II ions in the dichloromethane‐solvated form 12· CH 2 Cl 2 (Figure 16, right).…”

Vapochromic materials that show reversible color change driven by vapor adsorption/desorption have drawn significant attention because of their potential applications in chemical sensors and chemical‐switching modules. Among the vapochromic coordination complexes reported so far, a series of square‐planar PtII complexes has been studied and represents one of the most promising systems for practical chemical sensors. For such systems, the color of the complexes strongly depends not only on the ligand‐field splitting, but also on the intermolecular distance between the PtII ions. This microreview presents recent results of vapochromic complexes centered on one‐dimensionally stacked PtII systems from the viewpoint of the origin of their vapochromic behavior. The design of vapochromic materials has been facilitated because several useful chromophores, including metallophilic interaction between PtII ions, have been developed. However, it is still challenging to realize a specifically sensitive and selective response to targeted vapors. This review focuses on strategies to achieve assembled PtII complexes with selective vapochromic responses.

“…Vapo‐ and mechanoluminescent complexes in the solid state show reversible emission‐color changes in the visible or near‐infrared regions. These spectral shifts, as responses of VOCs or mechanical force, generally originate from molecular conformation changes in the solid state, e.g., metal–metal distance,3–22, 40, 41, 43–45 coordination of VOCs,23–26 trapped VOCs in a crystal lattice,27–29 weak noncovalent interactions (π–π interaction, hydrogen bonding, CH–π interactions),8, 11, 19, 20, 26, 30–36, 40, 43, 47 isomerization involving polymer complexes and oligomers,37 and planarization of the conjugated ligand 46. Up to now, a number of linearly‐coordinated Au I systems have been reported as vapoluminescent compounds3, 6, 9 or mechanoluminescent materials 39–41.…”

Tetrahedral gold(I) complexes containing the diphosphane ligand (dppb=1,2-bis(diphenylphosphino)benzene), [Au(dppb)(2)]X [X=Cl (1), Br (2), I (3), NO(3) (4), BF(4) (5), PF(6) (6), B(C(6)H(4)F-4)(4) (7)], and the ethanol and methanol adducts of complex 4, 8, and 9, were prepared to analyze their unique photophysical properties. These complexes are classified into two categories on the basis of their crystal structures. In Category I, the complexes (1-5) have relatively-small counter anions and two dppb ligands are symmetrically coordinated to the central Au(I) atom, and display an intense blue phosphorescence. Alternatively, the complexes (6-9) in Category II have large counter anions and two dppb ligands asymmetrically coordinated to Au(I) atom, and display a yellow or yellow orange phosphorescence. The difference in the phosphorescence color of the complexes between the Category I and II is ascribed to the change in the structure of the cationic moiety in the complex. According to DFT calculations, the symmetry reduction caused by the large counter anion of the complex in Category II gives the destabilization of HOMO (σ*) levels, leading to the red-shift of the emission peak. We have demonstrated that the symmetry reductions are responsible for the phosphorescence color alteration caused by external stimuli (volatile organic compounds and mechanical grinding).

Abstract.A platinum(II) complex Pt(DiBrbpy)Cl 2 (1) based on 4,4Ј-dibromo-2,2Ј-bipyridine ligand was synthesized and characterized. Interestingly, two solvated phases of 1 with different amounts of crystalline CH 2 Cl 2 molecules, 1·1/3(CH 2 Cl 2 ) (yellow) and 1·3/2(CH 2 Cl 2 ) (red), were obtained. In the solid state, 1·1/3(CH 2 Cl 2 ) exhibits a 3D supramolecular structure based on Pt(DiBrbpy)Cl 2 monomer and emits a weak yellow luminescence at 541 nm (579, sh).
