Triazatriangulenium (TATA) platforms have been used to prepare highly ordered, self-assembled monolayers of free- and vertically standing imines on Au(111) surfaces. Upon irradiation, the imines undergo trans-cis isomerization and a fast thermal reaction (t1/2 =0.58 s at 20 °C) back to the more stable trans form. It is known that the photochemical reaction proceeds through rotation of the C=N bond and the thermochemical reaction through inversion at the N atom. The imine motors, therefore, should be able to induce a net displacement of particles above the surface similar to cilia epithelia in nature.
三嗪并三嗪鎓（TATA）平台已被用于在 Au(111)表面制备自由和垂直站立亚胺的高度有序、自组装单层。光照后，亚胺发生顺反异构化和快速热反应（在 20°C 下 t1/2=0.58 s）回到更稳定的顺式形式。已知光化学反应通过 C=N 键的旋转进行，热化学反应通过 N 原子的反转进行。因此，亚胺马达应该能够诱导表面上方粒子的净位移，类似于自然界中的纤毛上皮。
