Abstract
The magnetic behavior of nickel-seamed C-propylpyrogallol[4]arene dimeric and hexameric nanocapsular assemblies has been investigated in the solid state using a SQUID magnetometer. These dimeric and hexameric capsular entities show magnetic differentiation both in terms of moment per nanocapsule and potential antiferromagnetic interactions within individual nanocapsules. The weak antiferromagnetic behavior observed at low temperatures indicates dipolar interactions between neighboring nickel atoms; however, this effect is higher in the hexameric nickel-seamed assembly. The differences in magnetic behavior of dimer versus hexamer can be attributed to different coordination environments and metal arrangements in the two nanocapsular assemblies.
