Paragraph 0023-0024, (2021/07/17)
The invention discloses a synthesis and purification method of a rigid cyclic tripyrrole compound with an intramolecular orthogonal structure. The method is based on a chain tripyrrole compound, and through a universal synthesis method, a four-membered ring compound with two orthogonal planes in a molecule is obtained. The preparation method comprises the following steps of starting from a pentafluorophenyl tripyrrole compound, carrying out bromination and oxidation reactions to obtain a bromine-terminated substituted conjugated tripyrrole compound, and then reacting the bromine-terminated substituted conjugated tripyrrole compound with a hydroquinone compound in an organic solvent to obtain a target product. Various substitution groups can be introduced into the hydroquinone compound, and huge scientific research potential can be shown in the aspects of photophysical property exploration, intermolecular interaction and the like. And more explorability and possibility can be brought to an oligomerization pyrrole compound system. The method has the characteristics of mild conditions, good conversion rate, high selectivity, flexible substituted group introduction and the like.
