摘要

A series of flavins were synthesized bearing electron-withdrawing and-donating substituents. The electrochemical properties of these flavins in a nonpolar solvent were determined. The recognition of these flavins by a diamidopyridine (DAP) receptor and the effect this receptor has on flavin redox potential was also quantified. It was found that the DAP-flavin binding affinity and the reduction potentials (E 1/2) for both the DAP-bound and ...
