Herein, phloroglucinol tristearate (PhgTS) was used to study the crystallization process due to its unique symmetric structure containing a benzene ring and three aliphatic chains. Spherulites of crystallized PhgTS from four solvents under diverse conditions were analyzed in detail and their formation process was studied. Maltese cross is shown by PhgTS spherulites obtained from aprotic solvents via polarized optical microscopy. In comparison, no Maltese cross can be observed from branch-like crystals formed from protic solvents. Independent on the microscaled morphology, lamellae were found to be the basic blocks constructing both PhgTS spherulites and branchlike crystals, which were formed predominantly by stacked PhgTS molecules. Although differential characters of the solvents did not affect the formation of lamellas, the solvents played a crucial role in the formation of selfassembled microscaled morphologies. In particular, the morphologies of spherulites were strongly affected by the concentration of PhgTS solutions, surrounding temperature and evaporation rate of solvents. Generally, a higher concentration of PhgTS led to more homogeneous spherulites, a lower evaporation rate resulted in more compact spherulites, and a higher surrounding temperature generated preferentially more ring-banded spherulites of PhgTS.

本文中，间苯三酚三硬脂酸酯（PhgTS）用于研究结晶过程，因为其独特的对称结构包含苯环和三个脂族链。详细分析了四种溶剂在不同条件下结晶的PhgTS的球晶，并研究了其形成过程。通过偏振光学显微镜从质子惰性溶剂中获得的PhgTS球晶显示马耳他十字。相比之下，从质子溶剂形成的分支状晶体中未观察到马耳他十字。独立于微观形态，片晶是构成PhgTS球晶和分支状晶体的基本嵌段，它们主要由堆积的PhgTS分子形成。尽管溶剂的不同特性不会影响薄片的形成，溶剂在自组装微尺度形态的形成中起关键作用。尤其是，球晶的形貌受到PhgTS溶液浓度，周围温度和溶剂蒸发速率的强烈影响。通常，较高的PhgTS浓度会导致更均匀的球晶，较低的蒸发速率会导致更紧密的球晶，而较高的环境温度会优先生成更多的带状PhgTS球晶。
