TL;DR: Three-dimensional porous crystalline polyimide covalent organic frameworks (termed PI-COFs) have been synthesized and show high thermal stability and surface area and high loading and good release control for drug delivery applications.

TL;DR: The correlation between hydrogen oxidation/evolution activity and experimentally measured hydrogen binding energy for polycrystalline platinum examined in several buffer solutions in a wide range of electrolyte pH is reported, strongly supporting the hypothesis that hydrogen binding power is the sole reaction descriptor for the hydrogen oxidation-evolution reaction on monometallic platinum.

TL;DR: Porous functionalized 3D COFs could be a promising new class of shape-selective catalysts in base-catalyzed Knoevenagel condensation reactions, according to their remarkable conversion and high size selectivity.

TL;DR: The onset potential of CO stripping on the four metals decreases with pH, indicating a stronger OH adsorption, which provides evidence against the promoting effect of adsorbed OH on HOR/HER.

TL;DR: It is reported that the imidization reaction can be used to prepare a series of polyimide (PI) COFs with pore size as large as 42 × 53 Å(2), which is among the largest reported to date, and surface area as high as 2,346 m(2) g(-1), which exceeds that of all amorphous porous PIs and isamong the highest reported for two-dimensional COFs.
