Dr. Zhang Siwei's research focuses on the luminescence mechanism of aggregation-induced emission (AIE) materials and their applications in biomedical diagnostics. AIE refers to the phenomenon where organic molecules do not emit light or emit weak light in their dissolved state, but their luminescence is enhanced after aggregation. AIE molecules typically possess rotors or isomerizable carbon-carbon double bonds. Recent developments in AIE molecules have primarily focused on purely organic small molecules, which limits the diversity of AIE systems. Dr. Zhang has conducted research on the AIE phenomenon in organometallic complexes, Schiff base structures, and inorganic systems, focusing on the structural characteristics of different systems. Their work has enriched the material systems and luminescence mechanisms of aluminescence in electron ion exchange (AIE), achieving the following innovative results in the field of AIE and related materials: 1) Expanding the research system of AIE from organic materials to inorganic materials, especially metal halide clusters and rare earth ion systems; 2) Revealing the influence of aggregation on low-frequency vibrational coupling, deepening the understanding of the AIE luminescence mechanism, and expanding the application of AIE molecules in fields such as bioimaging and photodynamic therapy; 3) Pioneering the use of sieved porous carbon materials as anode materials for sodium-ion batteries in the energy field, and promoting their industrial application. To date, they have published over 80 papers, including over 20 as first/corresponding author, icited over 5000 times on Google Scholar, with an H-index of 33. They have applied for 10 invention patents (including 4 international patents).
