Recent advances in mechanochromic luminescent metal complexes

Recent Advances in Phosphorescent Pt(II) Complexes Featuring Metallophilic Interactions: Properties and Applications

“…78 Finally, mechanoresponsiveness was also observed in Pt(II) heterometallic complexes, 79,80 while a recent review reports similar mechanoresponsive systems also based on other metals such as Au(I), Ag(I), Cu(I), and Ir(III). 81 Discussion of such derivatives is out of the scope of the present review.…”

Crystal structure of catena-poly[(μ2-3-(1H-pyrazol-4-yl)-5-(pyridin-4-yl)-1,2,4-triazole-κ N:N′)-bis(benzoato-κO)zinc(II)], C24H18N6O4Zn

“…Largely due to applications in gas storage and separation, luminescence, catalysis, magnetism and sensing, metalorganic framework/coordination polymer synthetic investigations have continued unabated over the past decade which drives the design and development of new metal-organic framework materials [4][5][6][7][8]. In that regard, the N-donor ligands and aromatic carboxylic acid are perhaps the most promising candidates, because they can interact with a metal surface by both π electrons and the lone-pair electrons at the nitrogen atom and oxygen atom.…”

Highly luminescent imidoylamidinato platinum(ii) complexes formed by the coupling of 1H-pyrazole-1-carboxamidine with nitriles used as reaction solvents

“…However, the addition of a drop of acetonitrile converts the amorphous phase to a crystalline state, which is slightly different from the unground original crystalline state. Although several Au(I) 14,21 and Pt(II) [14][15][16][17][18][19] complexes showing mechanochromic behavior have already been reported, the addition of solvent to the ground sample usually convert to the original crystalline state. Thus it is interesting that the reversible conversion between another crystalline state and amorphous phase was observed for the imidoylamidinato platinum complexes.…”

“…However, the number of the Pt(II) complexes showing mechanochromism is still limited. [14][15][16][17][18][19] We report here the crystal structures and photophysical properties of (2,2'-bipyridine)(imidoylamidinato)Pt(II) complexes in the solid state. + consists of Pt(II) ion, bpy, and imidoylamidinate formed by the coupling of amidine group with benzonitrile used as a reaction solvent, and it takes planar structure (Fig.…”
