研究领域

我的研究领域:

The excited state structures, reaction dynamics and molecular properties of biologically important molecules, organic compounds, metal-ligand coordinate compounds. Structure characterization of the short-lived transient species observed in the organic photochemistry. The conical intersectional dynamics probed by using the resonance Raman spectroscopy and CASSCF computations.

n       Conical intersectional dynamics

A conical intersection of two potential energy surfaces is the set of molecular geometry points where the two potential energy surfaces are degenerate (intersect) and the non-adiabatic couplings between these two states are non-vanishing. In the vicinity of conical intersections, the Born-Oppenheimer approximation breaks down, allowing non-adiabatic processes to take place. The location and characterization of conical intersections are therefore essential to the understanding to a wide range of reactions, such as photo-reactions, explosion and combustion reactions, etc. While significant progresses have been made in understanding conical intersection dynamics experimentally, the conical intersection region has not been accessed directly in most experimental studies to date and experimental evidence for the existence of conical intersection has mostly been circumstantial. The real-time study of the dynamics associated to conical intersections is still a major challenge to the latest techniques of ultrafast measurement. We have recently been using resonance Raman spectroscopy, a frequency domain analogue for real-time ultrashort pulse experiment, in conjunction with the advanced quantum mechanical CASSCF calculation to reveal the conical intersectional structural dynamics within or nearby the Franck-Condon region (FC) for various molecular systems, such as thiophene, pyrazine, thioanisole, 4-cyanobenzaldehyde, a,b-enones, nucleobases, etc.

n       Photoinduced Electron-Transfer and Structural dynamics

Photoinduced electron-transfer and structural dynamics are key processes important for photochemistry and theoretical chemistry, and have implications in material science, bio-systems, environmental science, etc. We have recently been carried out investigations of the photodissociation dynamics of nitroaromatics, heterocyclic halides, neucleo bases and neucleotides, aromatic carbonyl molecules, halogen-benzene complexes, metal-ligand complexes to investigate systematically how similar molecular system with different substitutents affect their photodissociation dynamics and energy partitioning. This project seeks to use a combination of experimental and theoretical studies to better understand how the systems (aromatic compounds, heterocyclic aromatic compounds, metal-ligand complexes), and the factors (molecular symmetry, substituents, ortho-/para-effects)  determine or manipulate the structural dynamics and the subsequent passway (photodissociation, photoisomerization, internal conversion, intersystem crossing, etc.) followed after the photoinduced electron-transfer.

n       Intramolecular Excited State Proton Transfer Reaction (IESPT)

IESPT reactions have been observed to play an important role in many chemical and biological systems, and have found many important applications in laser materials, polymer photostablizers, information storage devices, etc. We have recently used the resonance Raman intensity analysis as well as density functional theory calculations to better understand the Franck-Condon region proton-transfer dynamics of the model compounds 2-hydroxybenzaldehyde, 2-nitrophenol and their derivatives.  and their possible roles in the electronic excited state processes of biosystems.

n       Photodissociation and Photoisomerization of Polyhaloalkanes

Polyhalomethanes like CFCl3, CCl4, CHBr3, CHBr2Cl, CH2I2, CH2Br2 and CH2BrI have been observed in the atmosphere and are important sources of reactive halogen species in the atmosphere. Polyhalomethanes are also of interest in synthetic chemistry for cyclopropanation reactions. We have recently shown that ultraviolet photolysis of polyhalomethanes in room temperature solutions leads to appreciable formation of novel iso-polyhalomethane photoproduct species. The iso-diiodomethane species can act as the methylene transfer agent in photo-cyclopropanation reactions using photolysis of diiodomethane in the presence of olefins. We are using resonance Raman and time-resolved resonance Raman spectroscopy as well as density functional theory calculations to better understand the iso-polyhalomethane species and its chemical reactivity.
