Category: pyrazoles-derivatives. I found the field of Chemistry very interesting. Saw the article Synthesis and photophysical properties of butterfly-shaped dinuclear Pt(II) complex having NHC-based chelate ligands published in 2019.0, Reprint Addresses Umakoshi, K (corresponding author), Nagasaki Univ, Grad Sch Engn, Div Chem & Mat Sci, Bunkyo Machi, Nagasaki 8528521, Japan.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole.
A butterfly-shaped dinuclear Pt(II) complex having pyridyl-NHC chelate ligands and bridging Me(2)pz ligands was synthesized. The crystal structure of the Pt-2 complex showed short intramolecular Pt center dot center dot center dot Pt distance (3.129 angstrom) and unique packing structure containing one-dimensional infinite pore that was filled with solvent molecules. The absorbance was proportional to the concentration of Pt-2 complex and no significant bands appeared even in high concentration (up to 100 mu M). The Pt-2 complex showed bluish-green emission (lambda(max) = 459 nm) in the solid state at 298 K (lambda(ex) = 330 nm). TD-DFT calculation revealed that the lowest-energy absorption bands are mainly assigned to the combination of metal-to-ligand charge transfer (MLCT) and ligand-to-ligand charge transfer (LLCT) transitions.
