#. Research Topic & Interests
I. Photo-physical study for organic light materials
A study on unclear photo-physical behaviors of fluorescence, phosphorescence, room-temperature phosphorescence (RTP), thermally activated delayed fluorescence (TADF), and exergonic exciton harvest within the system. We have aimed to elucidate the underlying mechanism, governing these phenomena, with a particular focus on in-depth spectroscopic approaches.
A search for organic materials that exhibit a novel photo-physical mechanism.
The objective of this study is to discover material that demonstrate previously unexplored photo-physical properties.
II. OLED fabrication & characterization
Optical & electrical modeling; the classical/quantum exciton dynamics, Chance-Prock-Silbey model, and so on.
Device physics; identifying the key factors related to the roll-off and operational stability issues in highly efficient OLEDs. We have aimed to unravel the underlying mechanisms responsible for these phenomena and propose strategies to improve device performance and its stability.
III. Computation aided chemistry & engineering
Density functional theory (DFT) and ab initio quantum chemistry methods, including post-Hartree-Fock (HF) techniques, were employed to the molecular design and engineering for study.
Molecular dynamics (MD) simulation is employed to model the condensed solid films state, comprising a series of organic materials. Our major interests cover the following aspects; molecular deposition, molecular anisotropy, refractive index, electronic structure, and electron/hole mobility.
Simulation of the molecular clusters in a condensed solid-state, based on quantum-chemical/molecular mechanic (QM/MM) multi-scale method. We can also deal with the polymer or single molecule based charge-transfer (CT) system in the organic photovoltaic (OPV) & photodiode (OPD) area in the context of QM/MM scale.
A quantitative structure-activity relationship (QSAR) study based on machine learning to predict the key factors from the target molecular clusters. Our aim is to establish a precise correlation between the molecular structure and the activity or property of interest.
