Photomicrographs (×100) of: a) the blocky texture of the twist‐bend phase of 13 at 85.2 °C, b) the blocky texture alongside parabolic defects in the N_TB phase of compound 12 at 75.0 °C, c) the rope texture alongside parabolic defects in the N_TB of compound 13 at 65.0 °C, d) the well‐aligned rope texture of the N_TB phase of compound 12 at 52.5 °C confined in a 5±0.1 μm cell with antiparallel buffed polyimide alignment layers, e) the same conditions as (d) but with a λ‐waveplate inserted.
