Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The first synthesis</bold> of [28]hexaphyrin–silicon complexes has been achieved. The coordination sphere of the encapsulated Si^IV atom effectively twisted the skeletons of the complexes leading to features consistent with Möbius aromaticity. Selective desilylation of the [28]hexaphyrin–Si^IV complex under Tamao–Fleming oxidation conditions gave the free base β‐monohydroxylated [28]hexaphyrin analogue, which also demonstrated distinct Möbius aromaticity. This is the first example of a Möbius aromatic [28]hexaphyrin conformationally rigidified by intramolecular hydrogen‐bonding interactions. For more information, see the Communication of D. Kim, A.
