The synthesis and photophysical properties of a series of photostable unimolecular submersible nanomachines (USNs) are reported as a first step toward the analysis of their trajectories in solution. The USNs have a light-driven rotatory motor for propulsion in solution and photostable cy5-COT fluorophores for their tracking. These cy5-COT fluorophores are found to provide an almost 2-fold increase in photostability compared to the previous USN versions and do not affect the rotation of the motor.
本文报道了一系列光稳定的单分子潜水纳米机器（USNs）的合成和光物理性质，这是分析它们在溶液中的轨迹的第一步。USNs 具有光驱动的旋转马达，用于在溶液中推进，并且具有光稳定的 Cy5-COT 荧光团用于跟踪。与之前的 USN 版本相比，这些 Cy5-COT 荧光团的光稳定性提高了近 2 倍，并且不会影响马达的旋转。
