  text: Confinement within molecular cages can dramatically modify the physicochemical
    properties of the encapsulated guest molecules, but such host-guest complexes
    have mainly been studied in a static context. Combining confinement effects with
    fast guest exchange kinetics could pave the way toward stimuli-responsive supramolecular
    systems—and ultimately materials—whose desired properties could be tailored “on
    demand” rapidly and reversibly. Here, we demonstrate rapid guest exchange between
    inclusion complexes of an open-window coordination cage that can simultaneously
    accommodate two guest molecules. Working with two types of guests, anthracene
    derivatives and BODIPY dyes, we show that the former can substantially modify
    the optical properties of the latter upon noncovalent heterodimer formation. We
    also studied the light-induced covalent dimerization of encapsulated anthracenes
    and found large effects of confinement on reaction rates. By coupling the photodimerization
    with the rapid guest exchange, we developed a new way to modulate fluorescence
    using external irradiation.

  text: Dissipative self-assembly is ubiquitous in nature, where it gives rise to
    complex structures and functions such as self-healing, homeostasis, and camouflage.
    These phenomena are enabled by the continuous conversion of energy stored in chemical
    fuels, such as ATP. Over the past decade, an increasing number of synthetic chemically
    driven systems have been reported that mimic the features of their natural counterparts.
    At the same time, it has been shown that dissipative self-assembly can also be
    fueled by light; these optically fueled systems have been developed in parallel
    to the chemically fueled ones. In this perspective, we critically compare these
    two classes of systems. Despite the complementarity and fundamental differences
    between these two modes of dissipative self-assembly, our analysis reveals that
    multiple analogies exist between chemically and light-fueled systems. We hope
    that these considerations will facilitate further development of the field of
    dissipative self-assembly.

  text: Diamondoid nanoporous crystals represent a synthetically challenging class
    of materials that typically have been obtained from tetrahedral building blocks.
    In this issue of Chem, Stoddart and coworkers demonstrate that it is possible
    to generate diamondoid frameworks from a hexacationic building block lacking a
    tetrahedral symmetry. These results highlight the great potential of self-assembly
    for rapidly transforming small molecules into structurally complex functional
    materials.
