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 CPP framework.
