Abstract
This manuscript proposes a packing arrangement model for a co-mesogenic sidechain liquid crystalline copolysiloxane polymer copoly[4-allyloxy-benzoic acid [4′-2-(2-methoxyethoxy) ethoxy] biphenyl]-4-y1 ester-co-4-allyloxy-[(4-cyano)-4′-phenyl] carboxyl benzoate ester (copoly [(MS3BDBE2)-co-(MCN)]x/y depending on the relative molar composition of each mesogen. From the analysis of the thermal data, X-ray diffraction data, and solid state NMR spin-lattice relaxation (T1ρH) data, we have found two side chain molecules in the mesophase layer coming from the same or a different polymer backbone. They are presumed to be mixed and form a bilayer smectic C mesophase at lower MCN concentrations as well as at higher MCN concentrations.
