The First Homochiral Diamond‐Like Coordination Polymer Containing Cubane Cluster (Cu₄I₄) as Connecting Node and Cinchonine as Donor‐Acceptor (or Push‐Pull Electronic Effect) Building Block

The reaction of CuI with cinchonine (an organic donor‐acceptor chromophore) afforded a homochiral 3D diamondoid network [Cu 4 I 4 (cinchonine) 2 ] n ( 1 ) containing a cubane cluster (Cu 4 I 4 ) as a connecting node. This is the first homochiral coordination polymer with diamondoid nets containing a cluster as a connecting note. Its thermal stability and solid state optical properties such as fluorescence, circular dichroism and second‐harmonic generation response were also reported.
