摘要：

Schiff base ligands have long been successfully employed as ligands in combination with various metals to give catalysts capable of realizing a variety of synthetic transformations. One of the most widely used Schiff base ligands, the "salen'' ligand, has been extensively researched. Recently, there has been increased interest in pi-conjugated salen systems, known as "salphen'' ligands, as a result of the differences in reactivity of the complexes in catalytic applications compared with the salen analogues. Complexes of salphen ligands display interesting photophysical and supramolecular properties which are not always observed with salen systems as a result of their pi-conjugation. This tutorial review therefore describes the most significant advances recently made with salphen and related pi-conjugated ligand systems.
