Molecular magnets have been a very popular topic of research recently due to their potential applications in information storage, optoelectronics, and switching devices. However, before these materials can be used in these applications, a thorough understanding of how both structural and electronic perturbations affect magnetic exchange is needed. In order to systematically probe electron effects, a series of bis-phenoxy-bridged dicopper macrocyclic complexes was synthesized to determine the correlation between Hammett parameters of the substituent and the magnetic coupling of the compound. In addition to variable-temperature magnetic susceptibility measurements, crystal structures of the copper complexes will be presented, as well as a discussion on the synthesis of the complexes.
