    • Hotstage microscopy: The hot-stage microscopy experiments were performed with a Kofler hot stage (Reichert Thermovar, Vienna, Austria) attached to a Olympus BH2 polarization microscope (Olympus Optical GmbH, Vienna, Austria). The microscope images were recorded with an Olympus ColorView IIIu digital camera.

    • DSC: The DSC curve was recorded with a DSC 7 instrument (Perkin-Elmer, Norwalk, CT, USA) in a sealed 25 μL A1 pan (1.6 mg). The temperature of the instrument was calibrated with pure benzophenone (mp 48.0 °C) and caffeine (mp 236.2 °C), and the energy calibration was performed with pure indium (purity 99.999%, mp 156.6 °C, heat of fusion 28.45 J/g).

The thermal displacement parameters of the two terminal atoms in the chain (C5, C6) are large in the direction perpendicular to the chain, indicating a degree of lateral motion of this moiety. This motion is common for high temperature data on chain species and cannot be represented by a disordered model and does not affect the analysis or reliability. CCDC deposition number = 740144.
