The construction of stable covalent organic frameworks (COFs) for various applications is highly desirable. Herein, we report the synthesis a novel two-dimensional (2D) porphyrin-based sp2 carbon-conjugated COF (Por-sp2 c-COF), which adopts an eclipsed AA stacking structure with Brunauer-Emmett-Teller surface area 689 m2 g-1 . Owing to C=C linkages, Por-sp2 c-COF shows high chemical stability under conditions, even harsh conditions such as 9 m HCl and NaOH solutions. Interestingly, can be...
An oxygenation pathway: The title transformation involves a two-step process: selective step to generate aldehyde intermediates and subsequent condensation afford the imine products (see scheme). Detailed facts of importance specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They made available submitted by authors.

Abstract The construction of 2D and 3D covalent organic frameworks (COFs) from functional moieties for desired properties has gained much attention. However, the influence COFs dimensionality on their functionalities, which can further assist in COF design, never been explored. Now, by selecting designed precursors topology diagrams, porphyrinic (2D‐PdPor‐COF 3D‐PdPor‐COF) are synthesized. By model building Rietveld refinement powder X‐ray diffraction, 2D‐PdPor‐COF crystallizes as sheets...
Abstract 2D covalent organic frameworks (COFs) are receiving ongoing attention in semiconductor photocatalysis. Herein, we present a photocatalytic selective chemical transformation by combining sp 2 carbon‐conjugated porphyrin‐based framework (Por‐sp c‐COF) photocatalysis with TEMPO catalysis illuminated 623 nm red light‐emitting diodes (LEDs). Highly conversion of amines into imines was swiftly afforded minutes. Specifically, the π‐conjugation porphyrin linker leads to extensive absorption...
Abstract TiO 2 photoredox catalysis has recently attracted much interest for use in performing challenging organic transformations under mild reaction conditions. However, the scheme is hampered by fact that can only be excited UV light of wavelengths λ shorter than 385 nm. One promising strategy to overcome this issue anchor an organic, preferably metal‐free dye onto surface . Importantly, we observed introduction a catalytic amount redox mediator TEMPO...
Olefin-linked covalent organic frameworks (COFs) have exhibited great potential in visible-light photocatalysis. In principle, expanding fully conjugated COFs can facilitate light absorption and charge transfer, leading to improved Herein, three olefin-linked with the same topology are synthesized by combining 2,4,6-trimethyl-1,3,5-triazine (TMT) 1,3,5-triformylbenzene (TFB), 1,3,5-tris(4-formylphenyl)benzene (TFPB), 1,3,5-tris(4-formylphenylethynyl)benzene (TFPEB), namely, TMT-TFB-COF,...
Imines are important intermediates for the synthesis of fine chemicals, pharmaceuticals, and agricultural chemicals. Selective oxidation amines into their corresponding imines with dioxygen is one most-fundamental chemical transformations. Herein, we report a series benzylic atmospheric as oxidant on surface anatase TiO(2) under visible-light irradiation (λ>420 nm). The response this system was caused by formation complex through adsorption amine onto TiO(2). From analysis products specially...
Abstract Transition‐metal sulfides belong to an important subgroup of semiconductor photocatalysts that could promote a variety valuable redox reactions under mild conditions. One notable merit metal is their relatively smaller bandgaps than oxides, which in turn make sure many them can directly utilize visible light. Historically, the deployment for visible‐light‐induced organic transformations took place shortly after genesis research field heterogeneous photocatalysis. In this review, we...

The development of a facile synthesis and controllable layer stacking approach for covalent organic frameworks (COFs) is an important issue modulating their properties realizing application diversity. Herein, three COF isomers with different models (eclipsed AA, staggered AB, ABC stacking) were obtained by the reaction temperature solvent medium. Experimental theoretical calculations show that isomer at room kinetic product, while AA prepared solvothermal method thermodynamic product. Owing...
