环[18]碳的芳香性所产生的不寻常的稳定性可能被用来提供设计互锁系统所需的动力学捕获。分离互锁环和化学键合复合物的动力学势垒约为30 kcal mol（-1）。此外，环可以自由滑动，这是一个有前途的性质，为分子齿轮和马达的设计。
The unusual stability of cyclo[18]carbon arising from its aromaticity might be used to provide the kinetic trapping needed in the design of interlocked systems. The kinetic barrier separating the interlocked rings and the chemically bonded complex is about 30 kcal mol(-1). In addition, the rings can slide freely, which is a promising property for the design of molecular gears and motors.
