We present here the synthesis of one enantiomeric pair of metal–organicframework materials comprised of a unique multioriented double-helix structure from an achiral spirocenter ligand. Our study clearly shows that the chiral MOF material encompasses concurrently multiple nonlinear-optical functions in the solid state: the noncentrosymmetric structural feature brings the chiral MOF high second-harmonic-generation

We report four Zn-based coordinationpolymers (CPs), synthesized from three spirobifluorene (SBF) tetracarboxylate ligands, possessing different topologies and dimensionalities. Zn-SBF-1, Zn-SBF-2 and Zn-SBF-3 CPs have 2D crystal structures with an sql topology built from square planar ligands (L1 and L3) and paddle-wheels for Zn-SBF-1 or original dimers of zinc for Zn-SBF-2 and Zn-SBF-3.
