The article conveys some information:
Facile, environmentally-friendly fabrication of high-yield and stable covalent organic framework (COF) materials was a limitation to their large-scale production and application. Ball milling was used to synthesize COF by mechanochem. reaction between 1,3,5-triformylphloroglucinol (Tp) and melamine (MA) at ambient temperature Different routes (liquid-free, solvent-assisted and catalyst-assisted) and proportions of liquids (solvents or catalyst) were studied. Two morphologies were obtained when various amounts of liquid were added during grinding. The 2 forms were interwoven thread-shaped and exfoliative thin ribbon-like structures. Further, visible-light photocatalytic (λ > 400 nm) performance and mechanism of the 2 structures of COFs were studied. The exfoliative ribbon-like structures exhibited greater rates of photodegradation of phenol and retained 87.6% of initial photodegradation after being used 4 times. Addition of liquid catalyst not only improved crystallinity of the COF materials, but also enhanced rates of photocatalytic reactions. Photocatalytic activity of the exfoliative structure of TpMA synthesized by ball milling was comparable with that of the photocatalyst prepared using the solvothermal method, while time to prepare the catalyst was shortened by 36-fold and the amount of solvent used was reduced by 8-fold at room temperature Mechanochem. synthesis is a promising potential tool for large-scale production of COFs, which will make greater use of COFs for degradation of pollutants.

2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4) is a member of phloroglucinol derivatives. Phloroglucinol derivatives are a major class of secondary metabolites. Phloroglucinol compounds can be classified into monomeric, dimeric, trimeric and higher phloroglucinols, and phlorotannins.Application of 34374-88-4
