The Importance of a beta-beta Bond for Long-Range Antiferromagnetic Coupling in Directly Linked Copper(II) and Silver(II) Diporphyrins

摘要

Magnetic exchange coupling between distant metal centers is a major topic in the field of magnetochemistry.Although a great number of covalently linked oligomacrocycles (e.g.porphyrins or phthalocyanines) have so far been prepared,only a few such molecules have been tested for the exploitation of long-range magnetic coupling.
