Controlling magnetic communication through aromatic bridges by variation in torsion angle?

Dalton Transactions Pub Date: 2012-06-21 DOI: 10.1039/C2DT31292A

Abstract

A series of heteroaromatic bridging ligands are employed in the synthesis of a family of paramagnetic, heterometallic ring dimers. The extent of spin propagation between the rings via the organic conduit is investigated through micro-SQUID magnetometry and EPR spectroscopy from which conclusions over the mechanism of spin-communication are drawn.
