The pore apertures dictate the guest accessibilities of pores, imparting diverse functions to porous materials. It is highly desired construct crystalline polymers with predesignable and uniform mesopores that can allow large organic, inorganic, biological molecules enter. However, due ease formation interpenetrated and/or fragile structures, largest aperture reported in metal-organic frameworks 8.5 nm, value for covalent organic (COFs) only 5.8 nm. Herein, we a series COFs record values...
Two-dimensional conductive metal-organic frameworks (2D-c-MOFs) have attracted extensive attention owing to their unique structures and physical-chemical properties. However, the planarly extended structure of 2D-c-MOFs usually limited accessibility active sites. Herein, we designed a triptycene-based 2D vertically MOF (2D-vc-MOF) by coordinating 2,3,6,7,14,15-hexahydroxyltriptycene (HHTC) with Cu2+ . The 2D-vc-MOF(Cu) possesses weak interlayer interaction, which leads facile exfoliation...
Photocatalytic hydrogen (H2 ) evolution represents a promising and sustainable technology. Covalent organic frameworks (COFs)-based photocatalysts have received growing attention. A 2D fully conjugated ethylene-linked COF (BTT-BPy-COF) was fabricated with dedicated designed active site. The introduced bipyridine sites enable facile post-protonation strategy to fine-tune the actives sites, which results in largely improved charge-separation efficiency increased hydrophilicity pore channels...
Pore environment and aggregated structure play a vital role in determining the properties of porous materials, especially regarding mass transfer. Reticular chemistry imparts covalent organic frameworks (COFs) with well-aligned micro/mesopores, yet constructing hierarchical architectures remains great challenge. Herein, we reported COF-to-COF transformation methodology to prepare microtubular COFs. In this process, C3 -symmetric guanidine units decomposed into C2 hydrazine units, leading...
Through the introduction of sulfone groups, BTT-TPh-O-COF shows a 5-fold enhancement for photocatalytic detoxification sulfur mustard simulant, and was further used to fabricate highly active composite protective films.
Abstract Photocatalytic hydrogen (H 2 ) evolution represents a promising and sustainable technology. Covalent organic frameworks (COFs)‐based photocatalysts have received growing attention. A 2D fully conjugated ethylene‐linked COF (BTT‐BPy‐COF) was fabricated with dedicated designed active site. The introduced bipyridine sites enable facile post‐protonation strategy to fine‐tune the actives sites, which results in largely improved charge‐separation efficiency increased hydrophilicity pore...

As a new energy source that could replace petroleum, the global reserves of methane hydrate (combustible ice) are estimated to be approximately 20 000 trillion cubic meters. A large amount has been found under seabed, but transportation and storage gas far from coastlines technically unfeasible expensive. The direct conversion into value-added chemicals liquid fuels is highly desirable remains challenging. Herein, we prepare series iridium complexes based on porous polycarbazoles with high...
Task-specific porous polymer PIM-1-based quaternary ammonium iodide (PIM-1-AI) with available catalytic site has been obtained by functionalization of the precursor intrinsic microporosity PIM-1 and used in capture fixation CO .PIM-1-AI not only have 2 ability to (4.6 wt%, 273 K), but also can act as metal-free catalyst for conversion reaction without any co-catalyst prepare o various cyclic carbonates.The yields corresponding reactions catalyzed PIM-1-AI range from 87 % 99 at 2.5 MPa 90 C....
Cyano-bearing conjugated polycarbazoles PHN-1 and PHN-2 were efficiently prepared in high yields from corresponding monomers with paraand meta-configuration by oxidative coupling polymerization at room temperature, respectively.PHN-1 para-configuration exhibits higher porosity than counterpart PHN-2.Cyano groups the polymers further converted to containing tetrazole (PHN-1-TZ PHN-2-TZ) or amidoxime (PHN-1-AO PHN-2-AO) after treatment NaN /NH Cl 3 4 hydroxylamine aqueous solution,...
