Abstract
4-[(4-Cyanophenyl)acetylenyl]-2,3,5,6-tetrafluorophenyl 4-n-alkoxybenzoates, which contain a perfluorinated phenyl ring in their aromatic core system, exhibit nematic phases with a wide thermal range. In comparison with the homologues without fluorine, the introduction of the perfluorinated phenyl ring leads to the formation of a nematic phase and reduces the melting and clearing points.Keywords
