  • Polymer thin films that emit and absorb circularly polarised light are promising in achieving important technological advances, but the origin of the large chiroptical effects in such films has remained elusive. Here the authors demonstrate that in non-aligned polymer thin films, large chiroptical effects are caused by magneto-electric coupling, not structural chirality as previously assumed.

  • In biological systems, controlled molecular motion along a particular path is realized by protein motors that travel along microtubule filaments. Now, control of motion with light has been achieved in a synthetic supramolecular system, in which anionic porphyrin molecules move along the fibres of a bis-imidazolium gel upon irradiation.

  • A supramolecular polymer comprising stacked artificial chromophores to which zinc(II) complexes are appended is able to respond to enzymatic hydrolysis in aqueous solution. The assembly of molecules can twist reversibly and quickly in response to changes in the type of adenosine phosphate present.

  • Quantum biological electron transfer has potential in diagnostic and therapeutic settings. Here the authors report the triggered apoptosis of cancer cells using electricical input to wirelessly induce redox interactions at bio-nanoantennae in proximity to cancer cells.

  • Tying molecules together in a link results in tremendous stabilization of the radical species they can form. Six clearly distinguishable charged states — which can be interconverted reversibly — have now been observed in a densely cationic system.

  • The vortex in a stirring solution of supramolecular fibres is shown to induce chirality in an originally achiral system. The chiral sense is reversible and can be switched by changing the direction of stirring.

  • A scanning tunnelling microscope has been used to image multistep chemical reactions at a solid/liquid interface with single-molecule resolution. On reacting Mn(III) porphyrins with either O2 or a single oxygen donor, at least four distinct reaction intermediates and products were detected and their interconversion could be observed in real space and real time.

  • Semiconducting polymers are widely used in optoelectronic devices, in which their microstructure informs function. Here, the authors are able to resolve the molecular and sub-molecular ordering of polythiophene strands and thin films using atomic force microscopy, a significant step towards correlating polymer structure with device performance.
