Research data for artile 'The influence of molecular shape and electronic properties on the formation of the ferroelectric nematic phase'

The synthesis and characterization of two series of ferroelectric nematogens based on RM734 and having an additional methoxy group on the central phenyl ring are reported. Ferroelectric character of NF phase is confirmed by dielectric spectroscopy measurements, as well as by observation of polarization switching current. Stored dataset includes: (i) a txt file with numerical data (ASCI) for complex permittivity measured vs. frequency and temperature, (ii) zipped txt files (ASCI) with results of electric polarization measurements performed for compound 7137 (8-2-2 in manuscript) in function of temperature by switching current method and (iii) pdf file with published manuscript.
