摘要: In the cone conformation calix[4]arenes possess lower-rim polyphenolic pockets that are ideal for complexation of various transition-metal centres. Reaction these molecules with manganese salts in presence an appropriate base (and some cases co-ligand) results formation a family calixarene-supported [Mn(III)(2)Mn(II)(2)] clusters behave as single-molecule magnets (SMMs). Variation alkyl groups present at upper-rim allows expression degree control over self-assembly SMM building blocks, whilst retaining general magnetic properties. The different ligands around periphery core has effect extended SMMs.
