Description

Application

Pyrrole is used as one of the building blocks of biochemical macrocycles such as chlorins, porphyrins and corrins. It is also used for many technologically relevel applications such as in organometallic complexes and precursor molecules for self-assembled monolayers on metal surfaces.
