A Facile Stepwise Synthesis of New (Iso)nicotinoyl Spacers via Anisotropic OH...pi Interaction

摘要

Tuning of molecular topology of polypyridyl spacers via the balance of steric and inductive effects is an important field in supramolecular chemistry.Such polypyridyl ligands that can bridge two or more remote metal centers have been utilized in the synthesis of abiotic functional supramolecules that exhibit mixed valence,anion exchange,photoinduced electron or energy transfer,sensing,polymorphism,and magnetic exchange between paramagnetic centers.
