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.
