Two phosphorescent PtII-based cyclometalated complexes were co-crystallized with perfluorinated arenes to give 1:1 co-crystals. The X-ray study revealed that each of the complexes is embraced by arenesF to give infinite reverse sandwich structures. In four out of six structures, a dz2 orbital of PtII is directed to the arenesF ring via 蟺-hole路路路dz2[PtII] interactions, whereas in the other two structures, the filled dz2 orbital is directed toward the arene C atoms. Computed mol. electrostatic potential surfaces of the arenesF and the complexes, noncovalent interaction indexes for the co-crystals, and natural bond orbital calculations indicate that 蟺-hole路路路dz2[PtII] contacts (and, generally, the stacking) are of electrostatic origin. The solid-state photophys. study revealed up to 3.5-fold luminescence quantum yield and 15-fold lifetime enhancements in the co-crystals. This increase is associated with the strength of the 蟺-hole路路路dz2[PtII] contact that is dependent on the 蟺-acidity of the areneF and its spatial characteristics. This study involved multiple reactions and reactants, such as 2,3,4,5,6-Perfluoropyridine (cas: 700-16-3Application In Synthesis of 2,3,4,5,6-Perfluoropyridine).
2,3,4,5,6-Perfluoropyridine (cas: 700-16-3) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the 蟺-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the 蟽 bonds. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C鈥揌 in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Application In Synthesis of 2,3,4,5,6-Perfluoropyridine
