分子机器以其在微观层面上可精准操控的特点，在分子器件、纳米发动机、医疗、智能材料等领域具有重大应用价值并引起了广泛的关注。分子机器研究虽然已获2016年诺贝尔化学奖，但目前其离真正实用化还有很长的一段路要走。文章聚焦近年来分子机器在合成、表征、构建固态以及能做功功能体系等方向的研究成果，并对该领域的未来进行了展望。

Molecular machines can be precisely controlled at micro level and thus have significant application prospects in the fields of molecular devices, nano-engines, health care, intelligent materials and so on. Having won the 2016 Nobel Prize in chemistry, the research on molecular machines still has a long way to go before these beautiful tiny machines enter into practical applications. This article focuses on the research frontiers of molecular machines in recent years, including the fields of synthesis, characterization, constructing of solid-state devices, and setting up functional systems that can perform tasks. The prospects for future research are also raised.
