Guest Seminar - A Journey across Multiple Length Scales: From Molecular Frameworks, Mesoscopic Constructs to Functional Devices
Achieving novel device functions often involves material design across different length scales. This presentation would give a journey of material and device design from molecular to macroscopic level: (1) covalent organic frameworks formed by weaving organic threads that show high flexibility and metal-organic frameworks made into glassy states and shows microporosity; (2) mesoscopic constructs of molecular frameworks and nanomaterials where nanoscopic metal-organic framework crystallites enclose plasmonic nanocrystals to give synergistic functions; (3) generic electroluminescence device applicable to various molecular materials and quantum dots that can give mid-IR to UV light emission. Finally, the presentation would discuss the perspective of using the glassy metal-organic framework for solid-state ionics.
Dr. Yingbo Zhao obtained B.S. in chemistry from the University of Science and Technology of China in 2012, and Ph.D. in chemistry from the University of California, Berkeley in 2017 under the supervision of Prof. Omar Yaghi. He then conducted postdoctoral research in the Department of Electrical Engineering and Computer Science at UC Berkeley with Prof. Ali Javey from 2017 to 2021. He joined the School of Physical Science and Technology of ShanghaiTech University in August 2021 as an Assistant Professor. His research encompasses developing new materials for optoelectronic, energy storage, and biosensing devices.
