A zwitterionic α ‐cyclodextrin amino acid (picture, middle) undergoes solid‐state self‐assembly to give a novel helical column architecture (left), which is cross‐linked by hydrogen bonds into an array of parallel straight channels (right). Surprisingly, no hydrogen bonds are formed between proximate cyclodextrin units in the individual channels.
