Research
Our group focuses on using advanced spectroscopic techniques to explore the dynamics and properties of novel materials at the molecular level. By linking molecular structures and dynamics to functions and macroscopic properties, we aim to drive technological advancements.
Our research encompasses four main areas:
1. Ultrafast Spectroscopic Technique Development:
We are equipped with cutting-edge tools, including two-dimensional infrared (2D IR) spectrometers and femtosecond/nanosecond UV-Vis-NIR transient absorption (TA) spectrometers, alongside steady-state UV-Vis and FTIR spectrometers. Our objective is to advance ultrafast optical techniques by enhancing resolution and sensitivity across frequency, time, and spatial domains, enabling precise tracking of dynamic processes.
2. Mechanisms of Complex Reactions:
We focus on understanding photocatalytic and electrocatalytic reactions using ultrafast spectroscopy. By elucidating the mechanisms of these complex processes, we aim to control them, paving the way for industrial applications and innovations.
3. Properties and Dynamics of Novel Molecules:
In collaboration with synthetic groups, we study the photochemical properties and dynamics of innovative molecules and materials. Our research includes Carborin molecules (Prof. Haiping Xia, SUSTech), all-metal nanoclusters (Prof. Zhongming Sun, Fudan University), Aggregation-induced Emission molecules (Prof. Ben Zhong Tang, CUHK(SZ)), and Metal-organic-framework systems (Prof. Hai-Long Jiang, USTC; Prof. Xinchen Wang, FZU). Through ultrafast spectroscopy, we aim to uncover insights into the behavior and characteristics of these novel entities in condensed phases.
4. Polariton Chemistry:
We are invested in the emerging field of polariton chemistry, which leverages strong light-matter interactions within optical cavities to alter chemical reactions. Using ultrafast spectroscopy, we study the dynamics and mechanisms under vibrational strong coupling (VSC) conditions, where optical cavity modes strongly couple with molecular vibrational modes. This research holds potential for modifying chemical processes and developing novel applications.
Our overarching goal is to deepen our understanding of the fundamental principles that govern chemical reactions and material properties. By advancing this knowledge, we strive to create new technologies and applications that benefit society, contributing to scientific progress and innovation.
