A copper-organic framework as scavenger towards organic dyes pollutants via physical adsorption and visible-light photodegradation

Solvothermal reaction between Cu(NO3)2·3H2O and a V-shaped highly conjugated organic linker, a 2-periodic copper-organic framework of 1 has been deliberately obtained. Due to its uniquely architectural features, 1 demonstrates not only notably selective encapsulation of small-sized MB and MO dye molecules with high adsorption rate, but also efficient photodegradation activities through decomposing dyes of MB, MO and bulky phthalocyanine of reactive blue 21 under visible light irradiation.447
