Fabricating ultrathin two-dimensional (2D) covalent organic framework (COF) nanosheets (NSs) in large scale and high yield still remains a great challenge. This limits the exploration of unique functionalities wide range application potentials such materials. Herein, we develop scalable general bottom-up approach to facilely synthesize (<2.1 nm) imine-based 2D COF NSs (including COF-366 NSs, COF-367 COF-367-Co TAPB-PDA TAPB-BPDA NSs) (>100 mg) (>55%), via an imine-exchange synthesis strategy...
Hydrogen-bonded organic framework (HOF)-based catalysts still remain unreported thus far due to their relatively weak stability. In the present work, a robust porous HOF (HOF-19) with Brunauer–Emmett–Teller surface area of 685 m2 g–1 was reticulated from cagelike building block, amino-substituted bis(tetraoxacalix[2]arene[2]triazine), depending on hydrogen bonding help π–π interactions. The postsynthetic metalation HOF-19 palladium acetate afforded palladium(II)-containing heterogeneous...
Abstract The investigation on the catalytic properties of porous organic cages is still in an initial stage. Herein, reaction cyclohexanediamine with 5,15-di[3’,5’-diformyl(1,1’-biphenyl)]porphyrin affords a porphyrin tubular cage, PTC-1(2H). Transient absorption spectroscopy solution reveals much prolonged triplet lifetime PTC-1(2H) relative to monomer reference, illustrating unique photophysical behavior cagelike photosensitizer. long ensures high-efficiency singlet oxygen evolution...
Covalent organic frameworks (COFs) are promising crystalline materials for photocatalytic solar- to hydrogen-energy conversion due the tunable chemical structures and energy band gaps. Herein, we report a modification strategy improving activity of COFs. A benzene-1,3,5-tricarbaldehyde (BT)- benzothiadiazole derivative-based two-dimensional donor–acceptor (D-A) COF, denoted as BT-COF, were fabricated further modified by using an alternative electron-donating unit,...
