Pichaya Pattanasattayavong
- Asst. Professor
- Vidyasirimedhi Institute of Science and Technology (VISTEC), Thailand
Pichaya Pattanasattayavong obtained his PhD in Solid-State Physics from Imperial College London, UK, in 2015. In the same year, he joined the School of Molecular Science and Engineering, Vidyasirimedhi Institute of Science and Technology (VISTEC), Thailand, as Lecturer and was promoted to Assistant Professor in 2021. He is the Principal Investigator and Head of the Electronic Devices and Materials Innovation (EDM) research group at VISTEC. He has won numerous awards, such as 2019 Journal of Materials Chemistry C’s Emerging Investigator, 2020 Thailand’s Young Scientist Award, 2024 Chemical Society of Japan’s Distinguished Lectureship Award, and 2024 Thailand’s Young Materials Research Award. His research interests lie in the design/discovery of novel semiconductors based on coordination polymers, development of unique solution-based processing methods, and the applications of coordination polymers in opto/electronic devices. Pichaya also applies his expertise in developing practical technologies with industries in Thailand. One of the projects has led to the establishment of a spin-off company, Cleantech & Beyond, for which Pichaya is serving as CEO and CTO.
Research topics
Coordination polymers (CPs) offer vast possibilities for structural designs due to the many choices of metal atoms and customizable ligands. The structural versatility provides an enormous space for tuning properties, especially for electronic and optical characteristics. Based on materials design knowledge we have accumulated, our research group synthesizes and modifies CPs for a wide range of properties: systematically varying the structures from 3D to 2D and 1D; forming carrier transport pathways through matching frontier orbitals; and shifting optical absorption/emission from UV to NIR.
Furthermore, we specialize in processing the ‘unprocessables’. CPs are known for their insoluble nature, but our research has discover a new path by carefully selecting secondary ligands that serve as ‘coordinating solvents’. The unique method allows the deposition of CPs into high-quality, compact thin films that can be employed in various electronic and optoelectronic devices, such as thin-film transistors, solar cells, and photoelectrochemical cells. In addition, we also explore novel functional materials, such as metal nanoparticles for photoelectrochemical reactions and thermoresponsive composites for cooling and sensing applications.
