title: Charge matching on designing neutral cadmium-lanthanide-organic open frameworks for luminescence sensing.
abstract: Through careful consideration of charge matching, a simple replacement of metal ion from Cd(2+) to Ln(3+) in a building unit successfully transforms an anionic microporous framework into a series of isostructural porous neutral heterometallic frameworks [Cd(3)Ln(2)(btc)(4)(H(2)O)(6)(dmf)(4)]·x(solvent) (1; Ln=Tb, Eu, Nd, Gd, Sm, dmf=N,N'-dimethylformamide) by employing five different lanthanide ions. 1-Tb and 1-Eu exhibit interesting photoluminescent properties, and remarkably, 1-Tb can act as a luminescent sensor to identify organic solvents and metal ions.
