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: The observed photoelectrochemical activity of the 2D-COF films and their photocorrosion stability in water pave the way for a novel class of photoabsorber materials with versatile optical and electronic properties that are tunable through the selection of appropriate building blocks and their three-dimensional stacking.

TL;DR: The binding of mercury(II) to the sulfur‐limonene polysulfide resulted in a color change, which motivate application in next‐generation environmental remediation and mercury sensing.

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: The results suggest that tautomerization-induced electronic structure changes can be exploited in COF platforms to give rapid, reversible sensing in systems that exhibit long-term stability.
