The first example of a novel Azo-linked 2D COF with a hexagonal skeleton, high crystallinity and permanent porosity. The trans-to-cis photoisomerization can lead to the decline of Azo-COF crystallinity but cannot impact the pore size of Azo-COF. The current results will provide a strategy for designing smart COF materials.

Organic Framework

A novel one-dimensional covalent organic framework (COF-K) was firstly designed and synthesized through a Schiff-based reaction from a porphyrin building block and a nonlinear right-angle building block. The COF-K exhibited high BET surface area and narrow pore size of 1.25 nm and gave a CO2 adsorption capacity of 89 mg g−1 at 273K and 1bar.
