Abstract

Abstract : The front cover picture, provided by Jun‐Fa Wei et al., shows the instance of two aromatic double bonds and an imine double bond involved in a thermal 6π‐azaelectrocyclization, leading to triazacoronenes (TACs) under non‐acidic conditions. This method provides an effective complement to the previous methods and, meanwhile, represents a new synthesis tool for the TACs family. The picture depicts the synergetic cyclization process of π electrons to yield the products. Further details of this work can be found in the communication on pages 1651–1656 (Y.‐X. Sun, X.‐G.
