In situ grazing-incidence X-ray scattering shows that a monolayer of artificial rod-shaped dipolar molecular rotors produced on the surface of an aqueous subphase in a Langmuir trough has a structure conducive to a 2D ferroelectric phase. The axes of the rotors stand an average of 0.83 nm apart in a triangular grid, perpendicular to the surface within experimental error. They carry 2,3-dichlorophenylene rotators near rod centers, between two decks of interlocked triptycenes installed axially on the rotor axle. The analysis is based first on simultaneous fitting of observed Bragg rods and second on fitting the reflectivity curve with only three adjustable parameters and the calculated rotor electron density, which also revealed the presence of about seven molecules of water near each rotator. Dependent on preparation conditions, a minor and variable amount of a different crystal phase may also be present in the monolayer.

原位掠入射 X 射线散射表明，朗缪尔槽中水相表面产生的单层人造棒状偶极分子转子具有有利于二维铁电相的结构。转子的轴在三角形网格中平均间隔 0.83 nm，垂直于表面，在实验误差范围内。它们在杆中心附近携带 2,3-二氯亚苯基旋转器，位于轴向安装在转子轴上的两层互锁三蝶烯之间。该分析首先基于观察到的布拉格棒的同步拟合，其次基于仅使用三个可调参数和计算的转子电子密度拟合反射率曲线，这也揭示了每个旋转器附近存在大约七个水分子。根据制备条件，单层中还可以存在少量且可变量的不同晶相。
