Inspired by early reports concerning the association of Cyclodextrins to porphyrins targeting artificial enzymes, we designed new hybrids based on the association of a cyclodextrin to an expanded porphyrin (i.e. an hexaphyrin unit). Their combination affords a chiral confined space capped by a coordinating subunit with promising features for the development of biomimetic catalysts. Furthermore, such an association offers a range of new opportunities in the development of multi-responsive devices based on the accessible redox and (anti)aromatic states of the hexaphyrin subunit. We will discuss these properties spanning from tunable confined spaces to switchable (anti)aromaticity with a special emphasis on Möbius topology under chiral influence.
