N2 - New liq.-cryst. polyesters with 4-(phenylazo)azobenzene moieties as mesogenic side groups and a polyester backbone structure characterized by a systematic variation of the length of the flexible non-mesogenic main-chain segments were synthesized. The polyesters were investigated by DSC, polarizing microscopy, miscibility studies, and x-ray diffraction. With increasing no. of methylene groups in the backbone spacer, the thermal stability of the nematic and/or smectic phases first decreased and then increased. [on SciFinder (R)]
