Resum
Broadband dielectric spectroscopy (103 Hz-1.8 × 10 9 Hz) has been performed on the odd nonsymmetric liquid crystal dimers of the series a-(4-cyanobiphenyl-4'-oxy)-¿-(1- pyreniminebenzylidene-4'-oxy) alkanes (CBOnO.Py) with n ranging from 3 to 11, as a function of temperature. A previous thermal behavior study through heat capacity measurements has been made. Dielectric measurements enable us to obtain information about the molecular dynamics in the nematic mesophase as well as in the isotropic...
