Antimony- and bismuth-bridged
bipyridyls (dipyridinostibole and
dipyridinobismole; DPySb and DPyBi) were
prepared by the reactions of dilithiobipyridyl with dibromophenylstibine
and diiodophenylbismuthine. X-ray diffraction studies of the crystal
structures revealed a high planarity of the heterole ring. Cyclic
voltammograms obtained in acetonitrile indicated enhanced electron
affinity in comparison to a bridge-free bipyridyl. These compounds
showed weak fluorescence at room temperature and visible phosphorescence
at 77 K with emission maxima and lifetimes of λmax = 453 nm and τ = 1.03 ms for DPySb and λmax = 454 nm and τ = 0.26 ms for DPyBi,
respectively. Solid-state phosphorescence was also observed from these
dipyridinoheteroles at 77 K. Their copper complexes were prepared
by interaction with Cu2I2(PPh3)3, which produced red phosphorescence in the solid state at
room temperature.
