Synthesis and Biradicaloid Character of Doubly Linked Corrole Dimers

摘要

Cyclic pi-conjugated systems have attracted considerable interest in terms of their applications as molecular materials having conductive or nonlinear optical properties,as building blocks for supramolecular structures,and for complexation with metals or ions.Our group has developed meso-meso,beta-beta,beta-beta,triply linked porphyrin oligomers,which exhibit extremely low-energy electronic absorption bands that reach into the infrared region because of the extensive full pi-conjugation.
