摘要：

We have synthesized a family of conjugated diaminotriazine-functionalized receptors. Variation of distal functionality modulated the affinity of these receptors for flavin, demonstrating efficient electronic communication over a distance of 11 Angstrom. The origin of this communication was explored using DFT methodology. These calculations demonstrate that modulation of recognition in these systems is derived from a complex push-pull type mechanism.
