Regulation of Redox Properties of 6-Azaflavin by Hydrogen Bonding with a Receptor in Chloroform-Acetonitrile
A melamine derivative bearing two guanidinium ions binds 6-azaflavin via hydrogen bonds at N(1), C(2)=O, N(3)–H, C(4)=O, N(5), and N(6) positions, and affects considerably the redox properties in CHCl3 containing 20% (v/v) CH3CN.
