Investigations of both the ferroelectric and electroclinic properties of the new chiral palladium mesogen L,Pd have been performed. A comparison of the spontaneous polarization and the response time measured in the S,, phase of L,Pd and the corresponding values previously reported for other metallomesogens (see above) shows that the spontaneous polarization of L,Pd has the smallest value while the response time is essentially the same. The most striking features of L,Pd are the electroclinic properties. Despite the small value of the spontaneous polarization in the S,, phase, the field-induced tilt in the chiral smectic A phase (SA*) has a value of about 12" near the SA,-S,, phase transition on applying relatively moderate electric field. So far, such large induced tilt angles have been measured only in specially designed elcctroclinic liquid crystals. ["]
