Recent research:
1. Coordination chemistry and supramolecular chemistry of small biomolecule and cyclodextrin
1.1 Nucleotides are essential components of DNA and RNAs. They are chiral molecules that contain multiple functional groups, such as nucleobases, phosphate groups, and hydroxyls. So, they can coordinate to metal ions to exhibit complexity and diversity of their coordination chemistry and supramolecular chemistry, which makes them ideal candidates when mimicking biological systems and designing functional materials.

 


         

1.2 Cyclodextrins are cyclic oligosaccharides comprised of six or more α-1,4-linked D-glucopyranosyl residues. The shape-persistent hydrophobic cavities of these toroidal molecules allow encapsulation of suitable guests, and therefore, they represent a class of receptors that are ideal for the construction of hybrid assemblies. Their exceptional inclusion capabilities have led to their broad application in nanotechnology, pharmaceutics, medicine, and environmental science. 
               

 


2. Functional coordination complexes and polymers

The science of functional coordination polymers has become one of the most intense areas of study for chemists, physicists, and materials scientists due to their fascinating topological structures and potential applications in the fields of catalysis, photoluminescence, magnetism, et. al. over the last at least three decades. The construction of coordination polymers is mainly dependent on a combination of several factors, such as the properties and structure of ligand, using of auxiliary ligand, the ratio of reagent, templates and counter ions, the character of solvent, the coordination geometry of central metal atoms, the reaction temperature and pH, etc. Importantly, the subtle change of the above synthetic factors will produce polymorphism and supramolecular isomerism.

  2.1 Fluorescence coordination complexes for probing small molecules. A new method to construct functional MOFs has been developed by our group. A serial of novel MOF-74 analogs based on ingenious design and illustrate unique sensing and detection properties were prepared. They could be potential luminescent probes for detecting small molecules.

 
2.2 NIR fluorescent coordination complexes based on Schiff based ligand 
 


 

3. The studies of polymorphism and supramolecular isomerism based on crystallography
X-ray single crystal diffraction is the most powerful methods to study the structure of materials, which can help us to understand the relationship of structure and properties. It is fundamental research to design new materials with novel structures and tune the structures toward the expected properties.
