However, the exciton effect arising from the Coulomb interaction among electrons–holes cannot be disregarded. Exploring new approaches to regulate exciton dissociation on COFs to facilitate photocatalysis is significant. Within this work, localized defects were fabricated on the skeleton of the COFs by the one-step synthesis method of introducing monoaldehyde electron donors (pyrene, ferrocene, and triphenylamine). The formation of D–A configuration defects can directionally change the local electronic structure and charge distribution of COFs and induce enhanced dipole polarization, thus, promoting exciton dissociation and enhancing photocatalytic activity. Among them, the pyrene electron donor-constructed defective COF exhibited a 7.8-fold increase in the aqueous-phase oxygen-containing photopolymerization rate relative to the pristine COF, with a conversion rate of 80% within 30 min.23:T545,Electrochemical hydrogenation (ECH) of unsaturated carbon-heteroatom bonds is essential for chemical transformations but is often limited by a barrier-intensive surface hydrogen transfer process. The interfacial hydrogen bond (HB) network offers a promising pathway for proton transfer but requires addressing the challenge of nondirectional proton shuttling in three-dimensional space. Here, we create hydrophilic CuO_x islands on Cu foam (CF) and load electron-enriched Pd (Pd^δ-) single atoms as proton traps (Pd₁-CuO_x/CF) to guide a fast proton transfer along a modified HB network to enhance ECH efficiency. During ECH, hydrophilic CuO_x islands dissociate H₂O into protons and reconstruct the interfacial HB network for facile proton transfer, while the Pd^δ- single atoms reorient H₂O molecules to electrostatically attract and reduce protons to active hydrogen, enabling efficient substrate hydrogenation. With guided proton transfer, Pd₁-CuO_x/CF achieves 99% hydrogenation efficiency for C─Cl bonds, outperforming Pd₁-CF (69%) and CuO_x/CF (57%), and demonstrates high selectivity and Faradaic efficiency in hydrogenating C═O and C≡N bonds to produce valuable chemicals.24:T421,Two imine-based covalent organic framework photocatalysts with different building units, TPB-DMTA-COF and TAT-DMTA-COF, for photo-induced energy transfer reversible complexation-mediated radical polymerization (PET-RCMP) were developed and investigated, producing ideal polymers with accurate molecular weight and moderate dispersity under visible light irradiation. The chain extension and spatiotemporal control experiments revealed the high chain-end fidelity of polymers and the compatibility of RCMP processes in both bulk and aqueous system. Moreover, density functional theory (DFT) calculations verified that heteroatom-doped TAT-DMTA-COF exhibits higher activities for weakening C-I bond energy barrier, which promotes PET-RCMP polymerization performance. This work demonstrates that rational adjustment of building block for constructing COF heterogeneous photocatalyst can enhance the catalytic performance of PET-RCMP, providing a design methodology for the development of polymeric organic photoelectric semiconductor catalysts to mediate RCMP.25:T4cd,This arti
