A systematic synthesis of functionalized 1c polymers is possible starting from precursor polymers with phenolic groups. The esterification of these precursor polymers with chiral acids proceeds nearly quantitatively and produces polymers with cholesteric and chiral smectic C* phases. A further functionalization of these polymers with “NLO‐chromophores” produces polymers, which are suitable for second harmonic generation; a functionalization with crosslinkable groups leads to polymers, which act as piezoelements.
