abstract = {Covalent organic frameworks (COFs) are a unique class of porous materials built entirely from organic building blocks. As such, COFs unite the tunability of molecules with the robustness and optoelectronic functionality of extended solids-key requisites for (photo)catalysis. This LEGO (R)-like design of crystalline "molecular sponges" has captivated the imagination of chemists and inspired the first COF photocatalyst: a hydrazone-linked COF capable of harnessing visible light to drive the evolution of hydrogen from water. This commentary revisits that seminal contribution, published 11 years ago in Chemical Science (L. Stegbauer, K. Schwinghammer, B. V. Lotsch, Chem. Sci., 2014, \<bold\>5\</bold\>, 2789-2793, https://doi.org/10.1039/C4SC00016A), and reflects on its lasting impact. We survey the major advances that have shaped COF photocatalysis over the past decade and outline emerging opportunities and challenges, offering a forward-looking perspective on the role of COFs in solar energy conversion.},

abstract = {Developing strategies to enhance the utilization efficiency of catalytic sites in molecular catalysts has garnered increasing research interest in the field of molecular heterogeneous catalysis. The primary challenges in achieving this goal lie in the aggregation-induced site inaccessibility in molecular catalysts. Here, we present the synthesis of covalent organic framework-carbon nanotube (COF-CNT) core-shell nanohybrids as a platform to improve the site utilization of molecular catalysts in electrochemical CO2 reduction. COF shells with a thickness of 50-80 nm are uniformly grown on CNTs, ensuring a well-defined morphology with pores oriented perpendicularly to the CNT basal plane. The incorporation of molecular catalysts with COF-CNT nanohybrids enables their application as scaffolds in the electrochemical CO2 reduction. The best-performing sample exhibits a two-orders-of-magnitude increase in CO turnover frequency (TOF) compared to both pristine CoTPyP molecular catalyst and COF-366-Co, thus underscoring the effectiveness of the COF-CNT hybrid structure in optimizing catalytic site accessibility. The enhanced site utilization is further validated in other molecular catalyst systems, where exceptionally high TOF values-among the highest reported to date for electrochemical CO2-to-CO conversion-were achieved. Collectively, this study establishes COF-CNT nanohybrids as a promising strategy for advancing COF-based electrocatalysts and facilitating molecular catalyst applications in electrochemical energy conversion.},

abstract = {We report a systematic study of phenanthroline-Pd(II) complexes featuring electronically tuned amide substituents (alkyl: L1; carboxylic: L2/L3) for the transfer hydrogenation (TH) of trans-cinnamic acid (trans-CA) to hydrocinnamic acid (HCA) in imidazolium-based ionic liquids (ILs). The electronic effects of ligand substituents, hydrogen source (FA/TEA mixtures vs ammonium formate), and solvent environment on catalytic activity were evaluated. Alkylamide-substituted [Pd(L1)Cl2] displayed superior performance with FA/TEA via solution-phase hydride transfer, whereas electron-deficient [Pd(L2-L3)Cl2] were more effective with ammonium formate under a mixed homogeneous/heterogeneous regime. Ionic liquids significantly enhanced catalyst performance compared to the conventional organic solvent DMF, with minor changes in IL cations or anion causing substantial variations in conversion. Mechanistic studies, including MS, UV-Vis, NMR, electrochemistry (using Pt(II) analogues), and gas-evolution analyses, revealed that monoformate Pd intermediates and their evolution depend on the electronic properties of the ligands and the hydrogen donor, directing productive or unproductive pathways. This work highlights the delicate interplay between ligand design, hydrogen source, and ionic liquid microenvironment in controlling Pd-catalyzed transfer hydrogenation and provides a platform for designing efficient, tunable Pd-based TH systems.},
