✦ Synopsis

Abstract

The cover picture shows shape‐persistent first‐ and second‐generation polyphenylene dendrimers grown from a single benzophenone unit as core. To investigate the influence of the size and the density of the dendritic shell upon the reactivity of the core, “postsynthetic” chemical functionalizations with reagents of different size as well as alkali‐metal reduction of the encapsulated benzophenone were performed. Details are discussed in the article by K. Müllen et al. on p. 2523 ff.
