Abstract
Copper(I) complexes of di-2-pyridyl ketone (dpk), [Cu(PPh3)2(dpk)]NO3, [Cu2l2(PPh3)2(dpk)], and [Cu4I4(dpk)3], have been synthesized. The compounds were characterized by analytical and spectroscopic data. Their photocatalytic activity for the solar energy storage reaction norbornadiene (bicyclo[2.2.1]hepta-2,5-diene) to quadricyclane (tetracyclo[3.2.0.0.2.7.04,6]heptane) has been studied. The species [Cu(dpk)2]+, generated in situ from [Cu(CH3CN)4]+ and dpk, was found to be a stable photocatalyst at λ > 320 nm.Keywords
