Abstract
Crystallization processes of organic molecules remain inadequately understood compared to their inorganic counterparts. Recent discoveries challenging classical theories of crystallization underscore the complexity of organic crystallization mechanism. We herein report the growth of rod-shaped diethyl 2,5-dihydroxyterephthalate (DDT) crystals at room temperature. Utilizing in-situ atomic force microscope (AFM) imaging, we observed multifaceted crystal growth which includes coalescence, ripening, and the long-range migration of micro-sized DDT particles. Additionally, we noted their simultaneous disintegration into nanoclusters before integrating into larger crystals. This study offers fresh insights into the non-classical crystallization processes of organic molecules.
