Abstract:Mesogens that vary in shape anisometry have been investigated by 13C solid‐state NMR in the liquid crystalline phase to inspect the conformations. The molecules examined comprise of (i) rod‐like mesogen with three‐phenyl ring core and terminal hexyloxy chains, (ii) three‐ring core linked to the fourth phenyl ring via a spacer, and (iii) trimesic acid connected to three side arms core units through a spacer. The order parameter (Szz) values for the phenyl rings of the rod‐like mesogen are 0.65‐0.68, while the m… Show more
