Pyrrole is a five membered heterocyclic compound with the molecular formula of C4H5N. Pyrrole has a ring composed of four carbon atoms and one nitrogen atom. Pyrrole is easy to polymerize in the air. Pyrrole is the parent compound of many important biological substances (such as bile pigment, porphyrin and chlorophyll). Pyrrole scaffolds are widely used in biological and pharmaceutical fields. Pyrrole is a special heterocyclic scaffold, which exists in many natural products, drug molecules and pesticides, and has shown its application in materials science.

Pyrrole is a heterocyclic, aromatic, organic compound, a five-membered ring with the formula C 4H 4NH. It is a colorless volatile liquid that darkens readily upon exposure to air. Substituted derivatives are also called pyrroles, e.g., N-methylpyrrole.
Thiophene is a five-membered heterocyclic compound containing a sulfur heteroatom with the molecular formula C4H4S. Thiophene is aromatic and is very similar to benzene; electrophilic substitution reaction is easier than benzene, and it is mainly substituted at the 2-position. Thiophene ring system has certain stability to oxidant.
Benzene is an important organic compound with the chemical formula C6H6, and its molecule consists of a ring of 6 carbon atoms, each with 1 hydrogen atom. Benzene is a sweet, flammable, colorless and transparent liquid with carcinogenic toxicity at room temperature, and has a strong aromatic odor. It is insoluble in water, easily soluble in organic solvents, and can also be used as an organic solvent itself. The ring system of benzene is called benzene ring, and the structure after removing one hydrogen atom from the benzene ring is called phenyl. Benzene is one of the most important basic organic chemical raw materials. Many important chemical intermediates can be derived from benzene through substitution reaction, addition reaction and benzene ring cleavage reaction.
