  • Exciton diffusion length and directionality are important parameters in artificial photosynthetic devices. Here, the authors present a way to make crystalline chromophore assemblies with bespoke architecture, fabricating one exhibiting anisotropic exciton transport properties.

  • In heterogeneous catalysis, the diffusion of reactants to active sites is crucial, affecting both turnover frequency and product selectivity. This study presents a strategy to modulate reactant diffusion kinetics, thereby enhancing organic conversion efficiency in porous heterogeneous catalysts.

  • In heterogeneous porous systems diffusion rate is controlled by pore window sizes and concentration gradient. Here authors show that in a porous metal-organic framework system, the diffusion direction can be orthogonal to the concentration gradient.

  • In molecular solids, photoluminescence of dye molecules is often suppressed owing to excitonic coupling with adjacent chromophores. Here the authors use a computational method to predict the optimal alignment of naphthalenediimide linkers in metal–organic frameworks to afford J-aggregates, and demonstrate the same by fabricating highly photoluminescent thin film.
