Construction of a Porous Homochiral Coordination Polymer with Two Types of Cu sub()n sub(@)nAlternating Units Linked by Quinine: A Solvothermal and a Mechanochemical Approach

The polymer network: The reaction of quinine (QN) with CuI under solvothermal, as well as liquid-assisted grinding, conditions afforded a unique 1D homochiral coordination polymer {[Cu sub(4)( mu sub(3)-I) sub(4)(QN) sub(2)][Cu sub(3)( mu sub(3)-I) sub(2)( mu sub(2) -I)(QN) sub(2)] sub(2)} sub()n containing both triangular Cu sub(3)I sub(3) and cubane Cu sub(4)I sub(4) clusters as connecting nodes (see scheme). Van der Waals interactions between the adjacent 1D polymer chains lead to an extended quasi-honeycomb homochiral pillared 3D network with solvent-free 1D channels.
