Popis: A porous Zn(II) metal–organic framework (MOF) [Zn(H2L)(4,4′-bipy)0.5]n (1) has been selected and its luminescence sensing for cations and anions as well as the photocatalytic property against methyl violet have been explored. Luminescence studies indicated that 1 could be an efficient multifunctional fluorescent material for highly sensitive detection of metal cation Cu2+ and anions CrO42−. The luminescence intensity of 1 was found to decrease proportionately with increase in the concentration of Cu2+ and CrO42−. Furthermore, the photocatalytic property of 1 for degradation of the methyl violet (MV) have been explored and a possible photocatalytic mechanism have been proposed using density of states (DOS) and partial DOS (pDOS) calculations.
