The coating of organic molecules from the solution phase can result in directional crystal growth under certain conditions, even on a smooth isotropic surface and without the need of any kind of graphoexpitaxial preparation of the substrate. Based on reviewing the results from a variety of coating techniques and coating parameters, we identified that it is crucial for the coating speed to match the growth speed of the fastest growing crystal plane to achieve a high degree of directional crystallization.

从溶液相中涂覆有机分子在某些条件下可导致定向晶体生长，即使在光滑的各向同性表面上，且无需对衬底进行任何类型的图形外延制备。基于对各种涂覆技术和涂覆参数结果的回顾，我们确定涂层速度与生长最快的晶面的生长速度相匹配对于实现高度定向结晶至关重要。
