first examples of Pt(IV) anionic cyclometalated complexes. The molecular structures of the obtained complexes in the case of the NBu4[(Bzq)PtII(Thio)] and the NBu4[(Bzq)PtIV(Thio)2] complexes were confirmed by single crystal X-ray diffraction analysis. Furthermore, the electrochemical and photophysical properties of the two series of Pt(II) and Pt(IV) newly synthesised complexes were studied and DFT

Cyclometalated platinum(II) complexes are widely used as emitting materials in organic light emitting diodes (OLEDs).1,2 Platinum complexes with arylpyridine and diketonate ligands are rated among the most efficient electroluminophors.3,4 Platinum(II) complexes of this type with pyrazolonate ligands remain least studied.5,6 Howev er, it has been demonstrated with iridium(III) complexes that pyrazolonate ligands
Three strong solid state emissive cyclometalated platinum(II) complexes [Pt(C⁁N) (CH⁁N) (Cl)] (1) (C⁁N/CH⁁N = 2-phenylpyridine, C⁁N = bidentate and CH⁁N = monodentate), [Pt(C⁁N) (P⁁P)]Cl [P⁁P = bis(diphenylphosphino)ethane (2) and cis-1,2-bis(diphenylphosphino)ethene (3)] were reported. These were identified as ‘AggregationInducedEmission (AIE)’ active complexes based on controlled experiments. Cytotoxicity
We report the dissociation of a yellow emitting excimeric and AIE active Pt(ii) complex into the green emitting monomeric form after crushing with mesoporous silica (MS) followed by its encapsulation within the pores of MS.
Abstract Luminescent platinum(II) bis(pyrazolyl)borate complexes bearing orthometalated phenylpyridines (based on 2-phenylpyridine, 3-hexyloxy-2-phenylpyridine and (4-(pyridine-2-yl)-phenyl)methanol) and bis(pyrazolyl)borate ligands (employed as potassium dihydridobis(pyrazolyl)borate and potassium dihydridobis(3,5-dimethylpyrazolyl)borate) have been synthesized and characterized. By reaction of K2PtCl4 with
