Our research centers on aggregation science to engineer advanced luminescent materials by transforming molecular interactions into functional photophysical properties. Through precise control of aggregation states, we develop materials with tunable emission (visible to NIR), ultralong afterglow (hours), and circularly polarized luminescence for applications in bioimaging, phototherapy, optical security, 3D displays, and X-ray scintillation.

Our current research directions include:

· AIE materials for bioimaging and phototherapy: (i) Visible/NIR-I/II emissive AIE probes for in vitro organelle imaging and in vivo deep-tissue tracking; (ii) AIE photosensitizers for photodynamic/photothermal cancer theranostics.

· Ultralong room-temperature phosphorescence (RTP): Single-component and host-guest systems with persistent afterglow for time-resolved imaging, anti-counterfeiting, and encryption.

· Chiral luminescent materials: Rigid chiral scaffolds with circularly polarized phosphorescence for 3D displays, optical data storage, and chiral photonics.

· Transition metal complexes: Earth-abundant metal hybrids for OLEDs, triplet photosensitization, and radiation detection via scintillation.
