Programmable Molecular Switching and Electronic Properties
Speaker
Introduction
The Programmable Molecular Switching and Electronic Properties group investigates how molecular-scale changes can be translated into collective structural, mechanical, transport, and electronic behavior. Using quantum-chemical, atomistic, and multiscale simulations, we study molecular switches in polymers, self-assembled systems, interfaces, and surface-bound architectures. Our research follows the pathway from molecular switching and reconfiguration to collective response, electronic-property modulation, information transfer, and molecular programming. We aim to uncover the physical mechanisms by which local conformational or electronic changes propagate across scales and can be used to control organization, transport, mechanical response, and electronic function. Our long-term goal is to establish molecular switching as a design principle for programmable functional materials.
