摘要

Melamine derivatives bearing guanidinium ion (s) were synthesized as a flavin receptor using hydrogen bonds. The receptors bind 6-aza-10-dodecylisoalloxazine (6-azaflavin, 6- AzaFl) quite strongly via five or seven hydrogen bonds in CHCl3 or CHCl3-MeCN. Redox potentials of 6-AzaFl were considerably affected by hydrogen bondings of the receptors (positive shift: Δ E 1/2= 220-317 mV). Anionic semiquinone radical of 6-AzaFl was found to ...
