Magnetic characteristics of SIPPs. Aliquots (100 μL) of ODA-SIPPs (A, B), HDA-SIPPs (C, D), TDA-SIPPs (E, F), and DDA-SIPPs (G, H) were dried on Qtips® and measured using SQUID magnetometry. Hysteresis curves (M vs. H) are shown for SIPPs synthesized using either a 30-min (A, C, E, G) or 60-min (B, D, F, H) reflux time. The negative slope seen at high field is due to a diamagnetic contribution for the organic molecules (solvent and ligands). Insets show the ZFC (dashed line) and FC (solid line) curves for each of the SIPPs.
