General description

Pyrrole is a heterocyclic aromatic compound that can undergo electrophilic aromatic substitution.[1]

Application

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

The uneven conduction between myocardium and fibrotic tissue leads to dys-synchronous contraction, which progresses towards ventricular dysfunction. We synthesized a conductive
