Abstract

Abstract The synthesis of pentafluorophenyl end-capped polyynes up to an octayne has been developed based on the use of a Fritsch-Buttenberg-Wiechell rearrangement as the key step. UV/Vis spectroscopic analysis shows little change in the electronic nature of these structures as phenyl is formally replaced by pentafluorophenyl. The ability of pentafluorophenyl polyynes to function as supramolecular building blocks in host-guest ...
