Cao Lab

Dennis Cao

Organic materials research at a primarily undergraduate institution.

We are a synthetic organic chemistry group at Macalester College in St. Paul, Minnesota. Our research focuses on the design and synthesis of electron-deficient organic materials, with interests spanning cationic electron acceptors, novel dyes and fluorophores, and organic chromophore development.
