Layered Compounds with Polycyclic Aromatic Nuclei

Abstract

Recently a number of layered compounds, especially layered cyclophanes, with polycyclic aromatic nuclei have been reported. Such compounds, in which condensed aromatic rings are closely fixed with each other, or with other π-systems, often show unusual physical and chemical properties. In this review synthetic methods for layered cyclophanes are classified into eleven categories and reactivities of the compounds are described.
