    Exciton coupling between organic dyes is important for opto-electronic and photovoltaic devices and it is well-known that strong coupling occurs between equal chromophores. Here, Würthner and others show quadruple dye stacks that have strong exciton coupling between different chromophores within a heteroaggregate.

    Artificial light-harvesting systems cannot self-assemble into photon-capturing structures that can reversibly switch into an inactive state. Here, the authors describe a simple and robust dipeptide construct which self-assembles to fibrils, platelets or nanospheres with varying optical properties.

    Polymersomes are used in many applications, ranging from drug delivery to microfluidics, but controlling their shape is difficult. Here, Christianen and co-workers have precisely controlled polymersome shape via an out-of-equilibrium process and fully understood the mechanism of this procedure.

Here, the authors report a bifunctional organic probe that can bind to chiral hydroxyacids, and provide yield, enantiomeric excess and absolute configuration even with crude mixtures.

    Similarly to halogen bonding, the heavier chalcogens are capable of forming supramolecular links with electron rich sites. Here, the authors show that these forces can allow the formation of well-defined cyclic structures that are stable in solution and are capable of forming host-guest complexes.

    Activated atmospheric dioxygen is potentially an environmentally friendly oxidant. Here, the authors incorporate a flavin mononucleotide into a water soluble polymer, demonstrating single electron reduction of a metalloporphyrin centre, and subsequent activation of dioxygen for the oxidation of organic substrates.

    Cryptands and related molecules are macrocyclic polyethers capable of strongly binding cations. Here, the authors use orthoester exchange for the dynamic one-pot synthesis of crypates, which can bind cations and, given their constitutionally dynamic nature, can also be decomposed to release their guest.

    Certain chiral macroions have previously been shown to self-assemble into spherical structures. Here, the authors observe self-sorting of racemic macroions into enantiomeric ‘blackberry’-shaped structures, and furthermore show that the addition of chiral co-anions allows the formation of a single enantiomer.

    The limit external quantum efficiency of organic LEDs based on isotropically oriented iridium complexes is believed to be around 30%. But Kim et al. show that the emission from these complexes is in fact anisotropic, enabling them to increase the external quantum efficiency of these devices to 36%.

    Metal-organic frameworks are well studied for mass transfer applications, although rates of mass transfer for similar systems are shown to vary widely, attributed to surface barriers. Here, the authors quantitatively study this phenomenon and demonstrate that surface barriers are not intrinsic to the materials.
