Grace Han Research Group

University of California, Santa Barbara

What kinds of organic molecule designs enable reversible photon energy capture, storage, and triggered release in condensed phases? The Han Group develops molecular solar thermal energy storage systems based on anthracene and related chromophores for visible-light photon energy storage. The group designs photoswitches with controllable structural parameters to probe conformational freedom, absorption, and isomeric stability in condensed phases. Researchers combine synthetic chemistry with photophysical and materials characterization to measure switching dynamics and solid-state energy release mechanisms. Ongoing projects include optically controlled recovery and recycling of homogeneous organocatalysts using photoactive molecular systems.
