Covalent organic frameworks (COFs) are created by the condensation of molecular building blocks and nodes to form two-dimensional (2D) or three-dimensional (3D) crystalline frameworks. The diversity with different properties functionalities large number possible framework topologies open a vast space well-defined porous architectures. Besides more classical applications materials such as absorption, separation, catalytic conversions, interest in optoelectronic COFs has recently increased considerably. electronic both their linkage chemistry can be controlled tune photon absorption emission, create excitons charge carriers, use these carriers photocatalysis, luminescence, chemical sensing, photovoltaics. In this Perspective, we will discuss relationship between structural features properties, starting connectivity, layer stacking 2D COFs, control over defects morphology including thin film synthesis, exploring theoretical modeling structural, electronic, dynamic discussing recent intriguing focus on photocatalysis photoelectrochemistry.

Low-temperature direct ammonia fuel cell (DAFC) stands out as a more secure technology than the hydrogen system, while there is still lack of elegant bottom-up synthesis procedures for efficient oxidation reaction (AOR) electrocatalysts. The widely accepted d-band center, even with consideration width, usually fails to describe variations in AOR reactivity many practical conditions, and accurate activity descriptor necessary less empirical path. Herein, upper edge, εu, derived from model, identified an effective accurately establishing descriptor–activity relationship. Using PtCo alloy varying atomic composition example, εu value succeeds reflecting corresponding trends activity, showing striking linear correlation coefficient determination (R2) high 0.90. effectiveness established relationship verified experimentally. optimum electrocatalyst delivers excellent peak current density 74.04 A g–1 at 5 mV s–1, assembled DAFC generates power density, outperforming majority extensively reported systems. This work brings fundamental insights into between chemical electronic structure benefits rational optimization next-generation low-temperature DAFC.

Abstract Coupling ion exclusion and interaction screening within sub‐nanoconfinement channels in novel porous material membranes hold great potential to realize highly efficient sieving, particularly for high‐performance lithium‐ion extraction. Diverse kinds of advanced have been previously reported this goal but with moderate performance complex operations gained. Herein, these issues are circumvented by preparing the consecutive intact imine‐linked three‐dimensional covalent organic framework (i.e., COF‐300) via a simple solvothermal approach employing intrinsically interconnected sub‐1 nm one‐dimensional exceptional sieving. The synthesized charged angstrom scale ≈0.78 achieve an excellent Li + permeance (0.123 mol m −2 h −1 ) ultrahigh /Mg 2+ 36 binary system. experimental measurement theoretical calculation reveal that channel size right exactly between Mg enables restricted penetration. Meanwhile, affinity imine groups further strengthens fast permeability severely suppresses passage. In particular, framwork also remarkable separation during long‐term operation test without sacrificing trade‐off, demonstrating chemistry stability mechanical integrity under high‐salinity aqueous environment.
