Conjugated microporous polymers using a copper-catalyzed [4 + 2] cyclobenzannulation reaction: promising materials for iodine and dye adsorption

Abstract

A design strategy is disclosed to synthesize conjugated microporous polymers (CMPs) using a versatile copper-catalyzed [4+2] cyclobenzannulation reaction, which employs a diphenylethynyl terephthalaldehyde derivative 3 with a series of triptycene-based...

Bifunctional conjugated microporous polymer based filters for highly efficient PM and gaseous iodine capture

“…Compared to other CMPs reported before, CMPs@6 and CMPs@7 can reach a high level of adsorption capacity in a shorter period of time. 54…”

“…Compared to other CMPs reported before, CMPs@6 and CMPs@7 can reach a high level of adsorption capacity in a shorter period of time. 54 The same as the regeneration after PM filtration, the regeneration performance after iodine adsorption indicates the recyclability of CMPs@6 and CMPs@7. CMPs@6 and CMPs@7 which adsorbed gaseous iodine were washed with methanol and dried, and then, their capture of gaseous iodine was measured again.…”

Advances in porous organic polymers: syntheses, structures, and diverse applications

“…109 The Alameddine group prepared five CMP materials through Cu-catalyzed [4+2] benzannulations of 2,5-bis(phenylethynyl)tetraphthaladehyde with a series of 1,4-diarylethynyltriptycene derivatives. 110 The resultant CMPs 1-5 were microporous, with high BET surface areas (794 m 2 g -1 ) and pore volumes (0.63 cm -3 g -1 ), and displayed good I 2 uptake (166 wt%). Lin et al constructed CTT-POP1, a POP containing triaryl triazine and featuring intramolecular hydrogen bonds, that functioned as an adsorbent for the dye methylene blue because of its surface wettability and capability for π-π interactions.…”

Fluorinated Iron(ii) clathrochelate units in metalorganic based copolymers: improved porosity, iodine uptake, and dye adsorption properties

“…The former is an important reagent for various biological and industrial applications whereas the latter is considered to be a primary source of pollution in water resources. 8,[66][67][68][69] The capacity of CCP1-5 to adsorb MB and MEB was investigated by stirring at ambient temperature a 4 mg sample of a target copolymer in a 5 mL of a 5 mg L À1 aqueous solution of either MB or MEB dyes. The adsorption tests were performed by recording the UV-visible absorbance spectra at different time intervals (Fig.…”
