The photochemistry of 1,1-di(2-pyridyl) dihydrodioxin - Copper complexes.

1,1-di(2-pyridyl)dihydrodioxin demonstrated a great affinity to form metallocomplex with Copper ion( in valence state I and II), two nitrogen atoms offer unshared electron pair to Copper and form bidentant complexes. Transient absorption spectra of 1,1-di(2-pyridyl)DHD -- Copper complexes in acetonitrile at excitation wavelength 325 nm and time delays up to 1 nanosecond were measured.
