## Abstract **Summary:** We succeeded in the synthesis of azo side chain containing polysiloxanes with broad smectic C\* and A phases. In these polymers the phase transition temperatures can be shifted reversibly by up to 17 °C by irradiation with UV (__cis__) or VIS (__trans__) light. Thin films o

## Abstract A main‐chain elastomer was synthesized for the first time by a cross‐linking hydrosilylation of a cyclosiloxane with a new main‐chain liquid crystalline semiflexible polyether. Imposing a uniaxial mechanical field to the unstretched nematic polydomain sample results in a macroscopic ali

The direct and inverse piezoelectricity in single crystal ferroelectric liquid crystalline elastomers was measured by means of purpose-made experimental setups. As expected the observed effects depended strongly on temperature and the strength of the applied alternating electric field; additionally
