The state of the art and future of artificial supra-molecular machines
What is the future of artificial molecular machines?A recognized trend is toward the futuristic smart applications of"actively living"soft matter materials.Several recent examples by fundamental researches have been reflecting the preliminary principle,especially those based on supramolecular chemistry.Introducing noncovalent assembling sites onto artificial molecular machines is a promising way to enable discrete molecular machines to act as an ensemble that amplifies dynamics from molecular levels to supramolecular and even macroscopic level.This strategy has been proven robust in designing stimuli-responsive supramolecular soft matter and even enabling materials that can perform mechanical work as an output.This paper will focus on the topic of"supra-molecular machines",summarizing the state of the art and providing personal perspectives on the future possible opportunities and challenges of this field.
