Current Research Interests Controllable, reversible, and readable interconversion between two stable states of a molecule is a topic of fundamental and practical importance. Our research group is exploring structurally pre-organized molecular and supramolecular architectures as well-defined "conduits" for (a) electronic coupling between multiple redox-active centers or light-absorbing/emitting units, and (b) mechanical coupling between mobile components that are strategically placed within loosely-held molecular scaffolds. These studies involve iterative design processes guided by empirical observations and theoretical investigations, both of which we are actively engaged in. Together, we are advancing the frontiers of molecular devices for applications in chemical sensing, switching, transport, and actuation.
