摘要:
An undulated two-dimensional CTC-based covalent organic framework, CTC-COF, was synthesized through solvothermal reaction for the first time. This mesoporous material stacks in an eclipsed mode in the microcrystalline state. CTC-COF has a surface area of 1710 m(2) g(-1), with a pore width of 2.26 nm calculated by the NL-DFT modelling. The bowl-shaped core unit led to a larger surface area than its analogue, COF-5 constructed by planar subunits. This material has higher low pressure hydrogen uptake than other 2D COFs with similar structures, and even close to the 3D COF materials.
