ConspectusCovalent organic frameworks (COFs) are an emerging class of crystalline porous polymers and have received tremendous attention research interest. COFs can be classified into two-dimensional (2D) three-dimensional (3D) analogues. Resembling the architectures graphene, 2D conjugated exhibited promising prospects in many fields, such as gas storage separation, heterogeneous catalysis, sensing, photocatalysis, environmental remediation, drug delivery, energy conversion, so forth. However, efficient structural design for high-throughput production remains challenging.In this Account, we summarize our recent contributions to design, synthesis, application exploration COFs. First, raised "two-in-one" strategy facile synthesis imine with good reproducibility solvent adaptability. Thanks elaborate molecular strategy, could easily modulate topology fabricate COF films. In addition, developed two approaches stabilize by using planar building blocks donor-acceptor structures. We also proposed a skeleton engineering electrode materials, through which redox-active orthoquinone moieties were stepwise-incorporated skeletons isostructural imine-linked This enabled systematic investigations on series analogous structures but different numbers active sites storage, provides platform unveil underlying structure-property relationships. recently new kind arylamine-linked The electroactive diphenylamine linkages endowed these extended conjugation improved stability, conferred excellent pseudocapacitive performance. Moreover, tailor-made sulfur-rich introduced that synthesized selective introduction polysulfide or sulfonyl groups used Li proton conduction. At end, key challenges toward practical applications their future suggested. hope Account will evoke inspirations innovative work field near future, especially some burgeoning interdisciplinary areas.

Abstract Organic semiconductors offer a tunable platform for photocatalysis, yet the more difficult exciton dissociation, compared to that in inorganic semiconductors, lowers their photocatalytic activities. In this work, we report charge carrier lifetime is dramatically prolonged by incorporating suitable donor-acceptor (β-ketene-cyano) pair into covalent organic framework nanosheet. These nanosheets show an apparent quantum efficiency up 82.6% at 450 nm using platinum as co-catalyst H 2 evolution. Charge kinetic analysis and femtosecond transient absorption spectroscopy characterizations verify these modified have intrinsically lower binding energies longer-lived carriers than corresponding without unit. This work provides model gaining insight nature of short-lived active species polymeric photocatalysts.

Artificial photosynthesis of H2O2 from O2 reduction provides an energy-saving, safe, and green approach. However, it is still critical to develop highly active selective 2e– oxygen reaction photocatalysts for efficient production owing the unsatisfactory productivity. Herein, two new two-dimensional piperazine-linked CoPc-based covalent organic frameworks (COFs), namely, CoPc-BTM-COF CoPc-DAB-COF, were afforded nucleophilic substitution hexadecafluorophthalocyaninato cobalt(II) (CoPcF16) with 1,2,4,5-benzenetetramine (BTM) or 3,3′-diaminobenzidine (DAB). Powder X-ray diffraction analysis in combination electron microscopy a series spectroscopic technologies reveals their crystalline porous framework fully conjugated structure eclipsed π-stacking model. Ultraviolet–visible diffuse reflectance absorption spectra unveil excellent light capacity wide range 400–1000 nm. This, together enhanced photo-induced charge separation transport efficiency as disclosed by photocurrent response photoluminescence measurements, endows as-prepared COFs superior photocatalytic activity toward O2-to-H2O2 conversion under visible-light irradiation (λ > 400 nm). In particular, exhibits record-high yield 2096 μmol h–1 g–1 among COF-based impressive apparent quantum 7.2% at 630 The present result should be helpful fabricating high-performance low-cost visible-light-driven photosynthesis.
