Structural diversity of copper(II) coordination polymers based on tosylated isophthalic ligands

Two tosylated isophthalic ligands, namely, 5-tosyloxy-isophthalic acid (H2toip) and 5-tosylamino-isophthalic acid (H2taip) were synthesized. Self-assembly of CuII ions with H2toip and H2taip ligands under different reaction conditions (temperature, solvents, and auxiliary ligands) gave rise to three coordination polymers formulated as [Cu(toip)(py)2]n (1), [Cu 6(toip)6(H2O)6]n· 8n(H2O) (2), and [Cu6(taip)6(py) 4(dmf)2]n·n[(dmf)6(MeOH) 2(H2O)2] (3) (py = pyridine, dmf = dimethylformamide). Compound 1 is a one-dimensional (1D) coordination polymeric chain. Compounds 2 and 3 are two-dimensional (2D) coordination networks featuring very similar Kagome lattices based on the interconnection of paddle-wheel [Cu2(COO)4] secondary building units (SBUs) and toip2-/taip2- ligands. However, the arrangement of adjacent Kagome lattices in 2 and 3 are distinct, making them crystallize in different space groups and thereby have different crystal structures. Copyright

Dendrimers and Dendrimer Building Blocks with Trisubstituted Benzene and "Hexacyclene" as Core Units

The preparation of new dendritic compounds containing 1,3,5-substituted aromatic units or "hexacyclene" is described.Bulky dendrimers are obtained in few generations starting with polyfunctional core units like 1, 4, 5, 12, and hexacyclene (21).The dendrimers were synthesized by using both the divergent method (for 7) and the convergent method (for 13 and 22). 22 is the first dendrimer containing a crown unit as core. - Key Words: Dendrimers / Supramolecular chemistry
