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 [CU4I4(cinchonine)(2)]n (1) containing a cubane cluster (CU4I4) 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.
