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. We conclude some remarks about present challenges future prospects powerful architectural paradigm.

Abstract A poly‐phosphamide (POP) with a band gap of 2.8 eV is used for the photochemical conversion CO 2 into CH 4 and chemical organo‐epoxides cyclic carbonates. The Tauc plot Mott Schottky analyses indicate conduction potential at −1.49 V (vs NHE), much more negative than multi‐electron reduction lifetime photo‐excited electron found ns. On photoirradiation 420 nm light, POP in presence triethanolamine or ascorbic acid can selectively convert (≈99%) yield 4.6 mmol g −1 . visible‐light irradiation, drop charge‐transfer resistance (R ct ) an enhancement cathodic current further confirm photon‐harvesting efficiency POP. In situ, FTIR study identifies adsorption to possible reaction intermediate, like *‐CO, *‐CH OH. also behaves as catalyst carbonates under solvent‐free conditions 98% yield. After light‐phase dark‐phase reactions, be successfully recycled least five times without structural degradation. Herein, acts bi‐functional, recyclable polymeric organic material essential feedstocks mild conditions.
