单一手性烯烃铜(Ⅰ)配位聚合物

The solvothermal reaction of CuCl with R-(-)-1-allyl-3-methylpiperazine at 70 ℃ gives one-dimensional chain Cu-coordination polymer through olefin moiety binding to Cu atoms formulated as [Cu(C₈H₁₆N₂)Cl]. It is interesting to note that through Cu₂Cl₂ dimer unit 1 results in a supramolecular 3-dimensional coordination polymer. Powdered sample measurement of 1 reveals that 1 is second-harmonic generation (SHG) active compound.
