By means of copper catalyzed intramolecular coupling of the easily accessible 1,2-bis-(1-iodo-dipyrrin-9-yl)-ethanes and subsequent demetallation of the intermediate copper complexes corrphycenes could be prepared in nearly 40% overall yields.

A series of 2,2‘-bipyrroles has been efficiently synthesized using an improved synthetic approach based on Pd(0)-catalyzed homocoupling of various 2-iodopyrroles. This new synthetic approach takes place at room temperature and in the presence of water. Functional groups such as formyl, ester, and nitrile are able to survive these reaction conditions. Solvents are found to play an important role in

donor–acceptor dyads undergoing photoinduced electron transfer (PET), a direction or pathway for electron movement is usually dictated by the redox properties and the separation distance between the donor and acceptor subunits, while the effect of symmetry is less recognized. We have designed and synthesized two isomeric donor–acceptor assemblies in which electronic coupling between donor and acceptor is altered
