Research Interests

General research interests are molecular design, synthesis, modification and self-assembly of smart polymers for biomedical and optoelectronic applications, including biomaterials, molecular biosensors, smart gels, optoelectronic polymers, conjugated polymers, block copolymers, organic-inorganic hybrid materials, photovoltaic cells and self-assembly.

Currently, the Kim Research Group is studying the following areas:

• Biosensors: Sensitivity and selectivity are the most important parameters of a sensor. Nature provides high fidelity in biosynthesis. The unique combination of this specificity of the bio-system and the tunable properties of synthetic polymers would be a promising direction toward molecular sensors with high selectivity and sensitivity. We are developing molecular biosensors and bio-microarrays through bio-/synthetic hybrid systems for clinically important biological materials.
• Plastic Electronics: Conjugated polymers have become emerging materials for electronic devices. Their optical and semiconducting properties can be readily tunable through rational molecular design and chemical synthesis. We have been investigating structure-property correlation of conjugated polymers to establish molecular design rules to achieve high charge mobility, optimized energy levels, enhanced stability and fabrication versatility. Designer conjugated polymers for TFT, solar cells, thermoelectric, and LED are under development.
• Organic Phosphors: Recently we developed a molecular design principle to realize pure organic phosphor having high emission quantum yield even at room temperature with oxygen presence. By rationally designing directed heavy atom effects through intermolecular halogen bonding in crystalline aromatic carbonyl compounds we achieved highly efficient triplet generation and suppression of vibration dissipation. Controlling electron density of such organic phosphorescent materials we could achieve active color tuning as well. We are developing a second generation of organic phosphors to apply them to device applications.
