Abstract:

A liquid crystalline porphyrin was characterized by differential scanning calorimetry and hot-stage polarizing optical microscopy. The porphyrin was observed to undergo a complex exothermic phase transition called cold crystallization. This phenomenon did not occur when the molecule was heated for the first time but only upon heating the second time after cooling it down first. Therefore, the differential scanning calorimetry data were analyzed to study the kinetics and thermal behavior of the liquid crystalline porphyrins undergoing cold crystallization. The present report describes the results of non-isothermal analysis of liquid crystalline porphyrin by using three main methods including Avrami, Ozawa, and MO plots.
