摘　　要：Bioinspired micro‐/nano‐motors are artificial micro‐/nano‐machines that can convert various forms of energy to propel their movement[1].For example,the motion of some of these micromachines can be precisely controlled by application of external physical stimuli including magnetic,electric and acoustic fields[2,3].Inspired by the study of microorganisms,researchers have been exploring also the use of available chemical energy from the local environment to trigger and sustain self‐propulsion[4].Within this research direction,Metal‐organic frameworks(MOFs)—a class of extended materials synthesized via a modular approach from inorganic(metal clusters or ions)and organic linkers[5]—offer excellent opportunities for the design and synthesis of self‐propelled micromotors.MOFs typically possess ultra‐high surface areas that allow facile access to densely populated catalytically active sites imbedded within their pore networks.Through careful design these catalytic sites can be exploited to convert chemical energy into kinetic energy resulting in self‐propulsion of the MOF crystal[6].In addition,rigidity,density,crystalline pore organization and pore size of MOFs can be optimized to carry out a swimming‐type motion[7].
