  Triplet Emitters and Solar Chemistry

Platinum(II), gold(I) and copper(I) complexes can be developed to have long-lived and emissive electronic excited states for light-induced multi-electron atom transfer reactions and activation of small molecules of natural abundance. Of particular interests are the observation of metal-solvent/anion exciplex emissions from d10 metal complexes and light-induced inner-sphere H-atom abstraction reactions from Pt(II) complexes. Current research aims to design highly robust metal complexes having high energy and long-lived electronic excited states for light-to chemical conversion reactions. We intend to harness the phosphorescence of transition metal complexes as probes for molecular recognition reactions and for the detection of bio-molecules with practical interest. We are studying organic triplet emissions that are switched on through metal ion coordination. Applications of phosphorescent metal-organic compounds in organic optoelectronics are under active investigation. We are working on the design of robust triplet emitters derived from metals of large natural abundance in Mainland China.

Green Oxidation

We are studying the oxidation chemistry of ruthenium- and iron-oxo complexes. We are developing ruthenium-oxo catalysts for selective organic oxidations and aerobic oxidation of alkenes to aldehydes. Our present research is to develop new metal catalysts for green oxidations using hydrogen peroxide or dioxygen as terminal oxidant. The design of metal complexes covalently attached to water-soluble polymers will be pursued to achieve stereo-selective oxidations in aqueous media. We are studying the oxidation chemistry of iron-oxo complexes using robust oligopyridine and macrocyclic N-donor ligands, and are applying iron-oxo complexes for catalytic oxidation of alkanes, cis-dihydroxylation of alkenes and Wacker-type oxidation of alkenes using inexpensive terminal oxidants.

Metal-Nitrogen Multiple Bonds

The proposed research involves the synthesis and reactivity study of reactive metal-imido and -nitrido complexes, and electrophilic metal-nitrene complexes. Ruthenium, manganese and iron-imido complexes with diverse auxiliary ligands are prepared, identified by ESI-MS, and characterized by x-ray crystallography and/or DFT calculations. The reactivity of metal-nitrogen multiple bonded complexes towards organic substrates are studied. Of particular interest is to develop robust metal catalysts for selective activation of hydrocarbons via nitrene insertion to saturated C-H bonds. We are working to explore metal assisted cleavage of M-N N-M to metal-nitrido.

Metal-Carbon Multiple Bonds. Materials Science and Chemical Catalysis

We are studying the synthesis, spectroscopic properties and reactivity of highly reactive metal-carbon multiple bonded complexes. Our objective is to develop new methods for carbenoid transfer and insertion reactions that can be used for natural product synthesis and bio-conjugation reactions. We are also probing the electronic structures of M-(CC-R-)n and M=(C)n=CR2 by spectroscopic methods and molecular orbital calculations. We are working to develop new synthetic methods for the synthesis of multi-ring organic compounds with diversity and complexity via one pot tandem cascade carbon-carbon bond formation.

Chemical Biology of Inorganic Medicines

We have established a research platform for examining the biological mechanisms and therapeutic efficacies, particularly, the anti-cancer properties of various platinum-group metal complexes. The working principal is to create libraries of planar lipophilic cationic metal-ligand coordinated complexes, which are stable under physiological conditions, can easily be structurally modified, and display specific interaction/inhibition to important biological target(s).
