General description

Pyrrole is a heterocyclic aromatic compound that can undergo electrophilic aromatic substitution.

Application

Pyrrole was used in the electropolymerisation of macroporous conducting polymer films. It was also used to study the hydrogen-bond mediated coupling of 1,2,3-triazole to pyrrole.

Starting from a previously described aromatic oligoamide helically folded capsule that binds tartaric acid with high affinity and diastereoselectivity, we demonstrate the feasibility of the direct in situ modification of the helix backbone, which results in a conformational change that
