英文摘要	Synthesis of two trans-dihydroxy platinum(IV) porphyrins (TPP, tetraphenylporphyrin and F-20 TPP, tetrakispentafluorophenylporphyrin) by dimethyl dioxirane (DMD) oxidation of their PtII porphyrin precursors have been described. The oxidation state of Pt cation in such complexes was assessed by X-ray photoelectron spectroscopy and shown to be +4. More importantly, proton was found to promote the formation and stabilization of the trans-dihydroxy platinum(IV) porphyrins, as revealed by UV-vis spectroscopic results and single crystal structures. In addition, these trans-dihydroxy Pt-IV porphyrins were much easier to be reduced than their Pt(II) counterparts and capable to transfer oxygen atom to triphenylphosphine and thioanisol, which is important for further application of Pt(IV) complexes in catalytic reactions.; National Key Basic Research Support Foundation of China (NKBRSFC) [2015CB856301]; NSFC [20971007, 21101169, 21571007, 21271013, 21321001]; SCI(E); ARTICLE; zhangj271@ucas.ac.cn; 7; 785-792; 20
