Topic 1:

1. The precise construction of polycyclic aromatic molecules with unique topologies and multidimensional conjugated frameworks represents a cutting-edge frontier in synthetic chemistry and functional materials. Compared with planar polycyclic aromatics, rigid conjugated macrocycles with curvature or topological features (such as CPPs) exhibit remarkable differences in electronic structures, optical properties, and self-assembly behaviors, and demonstrate unique advantages in applications including optoelectronic devices, molecular recognition, and gas sensing. Our research group focuses on the following molecular systems:

2. 1) Design of novel conjugated macrocycles and their topological structures;

3. 2) Development of stimuli-responsive materials based on conjugated macrocycles;

4. 3) Applications of conjugated macrocycles in luminescent materials such as CPL/TADF;

5. 4) Construction of mechanically interlocked structures based on conjugated macrocycles.

Topic 2:

The design and construction of multidimensional conjugated frameworks provide significant opportunities for the development of novel functional molecular materials. Covalent organic frameworks (COFs), as a class of crystalline materials with high structural order and tunable architectures, present not only synthetic and methodological challenges but also unique advantages in charge transport, optical response, and interfacial assembly. Compared with conventional organic materials, COFs, with their diverse topologies and controllable functionalities, hold great promise in frontier applications such as organic electronics, environmental remediation, and molecular recognition. Our research group focuses on three main directions:

1）Design and synthesis of novel covalent organic frameworks (COFs);

2）Research on the applications of COFs in organic electronics;

3）Applications of supramolecular-based COFs in environmental remediation.
