Resolving and controlling excited-state dynamics by ultrafast spectroscopy
We use ultrafast spectroscopy to investigate photoactive materials in condensed phases across increasing levels of structural complexity, from molecules to atomically precise metal clusters and extended frameworks.
KEY SciENTIFIC QUESTION
How do electronic and vibrational motions determine photofunction—and how can we intervene?
Research Systems
Molecular Systems
Active control through vibrational strong coupling in optical cavities and perturbative laser control.
Condensed-Phase Metal Clusters
Main-group all-metal clusters and rare-earth clusters as atomically precise models.
Framework Materials
Metal–organic frameworks (MOFs) and covalent organic frameworks (COFs), resolving the dynamical mechanisms behind enhanced photofunction.
Spectroscopy Platform
Our platform leverages multi-dimensional ultrafast spectroscopy to resolve excited-state dynamics in condensed-phase photoactive materials. The methods platform explicitly includes: 2D IR, femtosecond and nanosecond transient absorption, and higher-sensitivity, higher-time-resolution, better pathway-resolution multi-dimensional ultrafast spectroscopy for electronic and vibrational states for the future.
Laboratory Facilities
Our research group at HKUST utilizes advanced spectroscopy instrumentation to resolve and control excited-state dynamics in condensed-phase systems.
