Half-substituted fluorocycloparaphenylenes with high symmetry: synthesis, properties and derivatization to densely substituted carbon nanorings

Abstract

Fluorinated cycloparaphenylenes (FCPPs) have attracted attention as electron-accepting CPPs as well as strained fluoroarenes. Herein, we report the synthesis and properties of novel FCPPs; F₁₆[8]CPP and F₁₂[6]CPP. Furthermore, the derivatization of F₁₆[8]CPP afforded a new carbon nanoring where sixteen pyrrole rings are densely substituted on the CPP framework.
