  • Artificial molecular systems can show complex kinetics of reproduction, however their integration into larger ensembles remains a challenge towards evolving higher order functionality. Here authors use show that self-reproducing lipids can initiate and accelerate octanol droplet movement and that reciprocally chemotactic movement of these droplets increases the rate of lipid reproduction substantially.

  • The cooperative motion of artificial molecular machines has led to materials that respond to light with changing shape but also with softening. Here the authors describe a phase-heterogeneous liquid crystal material in which the action of molecular switches leads to morphing and stiffening, by enhancement of interfacial tension.

  • Light and redox switches are of interest for responsive materials, actuators and robotics. Here the authors integrated a redox- and photoresponsive switch into a polymer hydrogel enabling reversible redox-switching with high spatio-temporal precision.

  • Overcrowded alkene-derived molecular motors convert light and heat into chirality-directed unidirectional rotary motion, but the efficiency of their photochemical isomerization remains limited. Now formylation of the motor core has been shown to boost all aspects of motor photochemistry by improving photochemical efficiency, diminishing competing processes and redshifting absorption.

  • Reversible nanoscale knotting and unknotting of a molecular strand can be used to control the handedness of helical organizations at macroscopic length scales. Dopant knotted and unknotted strands induce supramolecular helical structures of opposite handedness in achiral liquid crystals, and the left- and right-handed forms can be switched in situ.

  • Converting chemical energy into movement is essential to all forms of life, but the molecular processes are yet to be uncovered. Here the authors show a light-responsive reorientation behavior in liquid crystal droplets which stems from dynamic inversion of chirality from molecules to liquid crystals in confinement.

  • The natural world has long provided inspiration for the production of artificial, adaptive materials. This Review discusses how unravelling the rules of molecular motion has enabled integration of the cooperative, and sometimes synchronized, operation of light-responsive molecular machines, across length scales, into responsive and autonomous matter.

  • In this Review, we chart recent advances in the use of chemistry to control droplet motility in lipid solutions. The discussion includes a highlight on the interplay between chemical reactivity that occurs at the molecular level and motile behaviour that emerges at larger length scales.
