Abstract

C-alkylpyrogallol[4]arenes (PgCs) have been studied for their ability to form metal-organic nanocapsules (MONCs) through coordination to appropriate metal ions. Here we present the synthesis and characterization of a novel MnII/MnIII-seamed MONC in addition to its electrochemical and magnetic behaviour. This spectacular new MONC assembles from 24 manganese ions and 6 PgCs, whilst an additional metal ion is located on the capsule interior, anchored through the introduction of bridging nitrite ions. The latter originate from an in-situ redox reaction that occurs during the self-assembly process, thus representing a new route to otherwise unobtainable nanocapsules.
