The reaction of oligo(2-ethynylpyridines) (L1-L8) with copper(I) ions proceeded smoothly to afford tri-, tetra-, and pentanuclear triple-stranded helicates (CL1-CL8) in good yields. If a chiral ligand was used, the stereoselective self-assembly of chiral helicates with one particular chirality was achieved in the solid state. Racemization of copper(I) helicates was also observed in solution.

New oligo(2-ethynylpyridines) 1 are synthesized as novel building blocks for the construction of supramolecular systems by the coupling reaction of the novel dibromopyridines 2 with ethynylpyridines 3.
