Rooted in noncovalent interactions, dynamic covalent bonds and molecular self-assembly, supramolecular chemistry has evolved into supramolecular science through convergence with materials science, biology and allied disciplines, providing fertile ground for pioneering concepts and transformative technologies of the 21st century. Leveraging state-of-the-art advances and our sustained research achievements, our group pursues translational supramolecular chemistry, wherein supramolecular approaches are harnessed to propel the development of high-performance advanced materials (see Figure below). Our key research directions include: 1) Supramolecular materials for X-ray detection, 2) Supramolecular interlayer materials for organic photovoltaics, 3) Reprocessable dynamic covalent thermosets.

Students who are interested in organic chemistry, inorganic chemistry, physical chemistry or materials are strongly encouraged to join. Each student in my group will be trained in synthesis and techniques for manipulating air-sensitive compounds, powder diffraction analysis, single-crystal X-ray crystallography, thermogravimetric analysis, and spectroscopy (UV-vis, IR, Fluorescence).

Supramolecular Materials for X-Ray Detection. X-ray detectors are essential for medical diagnostics and homeland security. Conventional detector platforms suffer from weak bulk X-ray attenuation, mandating thick crystalline absorbers that bring rigid structures, high operating voltages and considerable cost. To tackle these limitations, our group develops supramolecular X-ray sensing materials with transformative advantages: mechanical flexibility, low fabrication cost, broadband response and high sensitivity.

Supramolecular Interlayer Materials for Organic Photovoltaics. Organic photovoltaics hold great promise for next-generation solar technologies, and rational interlayer engineering constitutes a viable route toward simultaneous improvements in device efficiency and stability. Our research targets functional supramolecular interlayer materials that reduce interfacial energy barriers, match well with high-performance active layers, and realize in-situ inner encapsulation. These materials jointly boost the power conversion efficiency and long-term operational stability of organic solar cells.

Reprocessable Dynamic Covalent Thermosets. Thermosetting polymers are widely deployed in industry and consumer goods, yet their permanently crosslinked covalent networks hinder reprocessing and recyclability. Dynamic covalent chemistry provides a powerful solution to this dilemma through stimulus-responsive bond exchange. We aim to construct dynamic covalent thermosets that balance mechanical integrity and service stability with multifunctional properties including self-healing, reshaping, thermoplastic-like reprocessability and controlled depolymerization for closed-loop chemical recycling.
