2D flexible metal–organic frameworks with [Cd2(μ2-X)2](X = Cl or Br) units exhibiting selective fluorescence sensing for small molecules†
Abstract
Two isomorphous 2D flexible metal–organic frameworks with [Cd2(μ2-X)2] (X = Cl or Br) units and dynamic 1D channels, which show tunable or switchable fluorescence signals in response to the loss of guest
