A ∗ phase and the smectic C ∗ phase. At a temperature of 105 ◦ C, just in the
smectic C ∗ phase, ferroelectric switching was achieved with a tilt angle of
26 ◦ . The mesogenic units were based upon the famous MHPOBC ferroelec-
tric material which had a switch angle of approximately 25 ◦ .Thusthisresult
demonstrated that the dendrimer is really acting as a collection of low-molar-
mass liquid crystals.
