“…For example, spacer segments play a key role in affecting the thermotropic behavior of liquid crystalline polymers. [4] In general, the polymerization of acrylate and methacrylate monomers, which can be used to prepare structurally well-defined polymers, is well known. This includes living-anionic polymerization, [5] group-transfer polymerization (GTP) [5] and atom transfer radical polymerization (ATRP).…”

To overcome some drawbacks of polyvinylpyridines, new monomers of acrylate and methacrylate type with pendant pyridine groups i.e., 4‐(3‐methacryloylpropyl)pyridine 1a and 4‐(3‐acryloylpropyl)pyridine 1b were successfully prepared, although it turned out to be challenging work to synthesize the acrylate monomer 1b. First polymerization studies showed that the new monomers could be polymerized easily by atom transfer radical polymerization (ATRP). The new polymers show excellent characteristics, such as very good solubility, low glass‐transition temperature, and easy quaternization.

“…On the other hand, liquid crystalline polymers, especially the ones incorporating calamitic moieties, belong to systems of wide interest. They combine the unique features of low molecular weight liquid crystals with increased thermal and mechanical stability of the mesophase and the possibility of macroscopic alignment, allowing to study the self-organization of the discotic mesogens, in order to investigate the oriented macroscopic structures [18]. Side chain polymers based on discotic mesogens have been much less explored and it concerns in particular systems based on flexible, linear polysiloxanes with triphenylene moieties.…”

Abstract. Side chain discotic polysiloxane with 2,3,6,7-tetrakis(hexyloxy)-10-methoxytriphenylene-11-undecanoate moieties is synthesized by hydrosilylation reaction. The phase behavior and thermooptical properties of the polysiloxane and the side chain precursor 2,3,6,7-tetrakis(hexyloxy)-10-methoxytriphenylene-11-undecanoate are examined by polarizing optical microscopy, thermooptical analysis, differential scanning calorimetry and wide angle X-ray scattering studies. A columnar planar alignment of LC in the layers has been determined. The pronounced alignment makes this polymer a promising material for application in optoelectronic devices. The differences in phase transitions and morphology between the triphenylene precursor and the discotic polysiloxane are discussed.
