Two metal-organic frameworks based on a flexible dithioether spacer with luminescence and sensing properties

Two isostructural metal organic frameworks, [M2(4-bpytm)(bdc)2] [M = Zn (1), Cu(2)] was synthesized under hydrothermal reaction. 1 and 2 showed 3-fold interpenetrated 6-connected pcu topologies based on bimetallic tetracarboxylate units with one-dimensional channels. The luminescence properties of 1 are investigated systematically.278
