TL;DR: Two-dimensional covalent organic frameworks (2D COFs) offer broad monomer scope but are generally isolated as powders comprising aggregated nanometer-scale crystallites, but it is found that 2D COF formation could be controlled using a two-step procedure in which monomers are added slowly to preformed nanoparticle seeds, which should enable a broad exploration of synthetic 2D polymer structures and properties.

TL;DR: An operando TEM electrochemical liquid cell is developed, providing the configuration of a real battery and in a relevant liquid electrolyte, and discovered new insights different from the open cell configuration-the dynamics of the electrolyte and, potentially, a future quantitative characterization of the solid electrolyte interphase layer formation and structural and chemical evolution.

TL;DR: Homogeneous polymerization conditions for boronate ester-linked, 2D COFs that inhibit crystallite precipitation are reported, resulting in stable colloidal suspensions of 2DCOF nanoparticles, and structural control provides new opportunities for understanding COF formation and designing morphologies for device applications.

TL;DR: First in situ high spatial resolution measurement coupled with real-time quantitative electrochemistry to characterize SEI formation on gold using a standard battery electrolyte demonstrates that a dendritic SEI forms prior to Li deposition and that it remains on the surface after Li electrodissolution.

TL;DR: Single crystal studies of two 2D MOFs hold promise as molecularly tunable platforms for fundamental science and applications where porosity and conductivity are critical, and reveal that these MOFs are not isostructural as previously reported.
