Linker-Dependent Conformational Switching in Side-Chain-Type Ferrocene-Functionalized Nanohoops.
We report the synthesis of two ferrocene-tethered side-chain nanohoops, Fc[8]CPP-L and Fc[8]CPP-M, via a streamlined shotgun macrocyclization protocol. Systematic variation of the tether length uncovers an interesting structure-property relationship: Fc[8]CPP-L exhibits coexisting intra- and intermolecular ferrocene in...
