Metal-organic frameworks
1 and
2, derived of rigid aromatic dicarboxylic acid and flexible linear linkers, are isostructural, which possess two-dimensional layer frameworks and exhibit good photocatalytic activities under visible irradiation. Different photocatalytic activities have been analyzed based on the diffuse-reflectance UV/Vis spectra.
