Ionic liquids used for synthesis of supramolecular isomeric open-frameworks as photocatalysts for visible-light-driven degradation of organic dyes

Two supramolecular isomeric anionic porous coordination frameworks synthesised using ion liquids contain similar linear trinuclear zinc motifs but exhibit quite different (4,7)- and (4,6)-connected topologies. Isomer 1 can degrade methylene blue (MB) effectively under UV-light-irradiation, but isomer 2 showed remarkable visible-light-driven degradation of diverse organic dyes.
