Design, synthesis, and characterization of novel high-spin species are critical for advancing the field of molecular magnetism, and subsequently creating new magnetic materials. As a means of grasping an understanding of how it is that one can control the electronic, hence magnetic interactions within a high-spin species, this study focuses on structure- property relationships in a series of bis(semiquinone) biradicals. The biradical moiety is the simplest of exchange-coupled systems. As electron-withdrawing, -donating and neutral substituents are placed on the coupler or spin carrier fragment of the biradicals under study, it is shown that there is a substituent effect operating within the series of ferromagnetically coupled m-phenylene bis(semiquinone) moieties. |
