major research directions:

1．Framework polymer synthesis; construction of polymer with new topology; polymer-crystalline-material hybrid systems

2. Smart materials: artificial muscles, motors, sensors, etc.

3. Design and construction of high-efficiency separation media: (1) column separation media based on porous framework materials (MOFs, COFs, HOFs, and cages) for light hydrocarbon gas separation or chiral separation; (2) the synthesis and new performance studies (separation, fuel cell separators, etc.) of membranes based on porous framework.
