Abstract

Puzzling out the intricacies associated with formation of supramolecular structures provides insight into and control of the self-assembly process. Such control may allow tailoring of these structures for specific applications. Herein we report the results of coordinated magnetic, solid-state and solution-phase studies carried out to investigate the mechanisms of formation and possible magnetic applications of metal-seamed pyrogallol[4]arene nanocapsules. SANS solution-phase studies and single-crystal XRD analyses demonstrate that varying the temperature, metal and solvent can control formation of specific capsular entities. The SQUID magnetometer data indicate a clear difference in the saturation magnetization of the dimeric and hexameric nikel MONCs. Moreover, the SQUID magnetometer and SANS analyses synergistically reveal the presence of a third, larger nanocapsular assembly.
