C10GL ( ) is liquid at room temperature, exhibiting an endothermic peak due to type I crystallization in the first cooling. In the first heating, the observed sequence was melting of type I crystal, type II crystallization (cold crystallization), and type II crystal melting. As the heating rate increased, the temperature of the exothermic peak due to cold crystallization rose, overlapping with the endothermic peak from subsequent melting of crystals, causing the disappearance of distinct peaks at a heating rate of 20°C/min. The cold crystallization temperature is near 0°C, suggesting its potential application as a heat storage material for ice melting.
