Achiral polysiloxanes with para-alkoxybenzoic acid side chains can bind many molecules of an optically active trans-stilbazole with hydrogen bonds. The resulting, self-assembling system 1 has ferroelectric properties which can be regulated by the number of stilbazole units per polymer molecule and the length of the (CH2)n spacer.
