Research Interests

My general interests are supramolecular chemistry, materials science, and nanotechnology:

  • Developing nanoparticle-based ultrasensitive sensor systems for metal ions and biological molecules Designing novel nanomaterials with high catalytic activity and recyclability
  • Synthesizing low-dimensional nanomaterials
  • Developing lanthanide-doped fluorescent nanoparticle probes

 

Research Highlight

Ref: Xu, H.; Chen, R. F.; Sun, Q.; Lai, W. Y.; Su, Q. Q.; Huang, W.; Liu, X. G., Recent progress in metal-organic complexes for optoelectronic applications. Chem. Soc. Rev. 2014, 43, 3259-3302.

The metal-organic complex offers unique optical and electronic properties arising from the interplay between the inorganic metal and the organic ligand. The ability to modify chemical structure through control over metal-ligand interaction on a molecular level could directly impact the properties of the complex. When deposited in thin film form, this class of materials enables the fabrication of a wide variety of low-cost electronic and optoelectronic devices. These include light emitting diodes, solar cells, photodetectors, field-effect transistors as well as chemical and biological sensors.
