摘要

The physical properties of biaryl-containing compounds are known to be highly dependent on molecular geometry. We report the syntheses and fundamental spectroscopic study of two donor–acceptor biaryl lactone (6H-benzo [c] chromen-6-one) pH-driven switches. These compounds have been determined to rapidly and efficiently switch between two geometric states upon cycling of acidic or basic stimuli. The planar lactone state exhibits enhanced ...
