Abstract:
The reaction of CuI and 3,6-bis(diphenylphosphino)pyridazine (dppz) in MeCN leads to the wheel-shaped complex [Cu8I8(dppz)6], assembled from four [Cu2I2] units and six dppz ligands. This complex exhibits thermochromic luminescence with emission colors ranging from red (300 K) to deep red (77 K). When carried out in the presence of PPh3, the reaction of CuI with dppz gives a non-emissive cage-like complex [Cu2I2(dppz)3], in which two CuI units are P,P′-bridged by three dppz ligands.
