The photochemistry of Pyridyl dihydrodioxin - Copper complexes.

Dihydrodioxine conaining pyridine rings in its structure demonstrated a great affinity to form metallocomplexes with Copper ion (in valence state I and II), nitrogen atoms on pyridines offer unshared electron pair to Copper and form bidentant complexes. Transient absorption measurements and mass spectra of those Copper complexes in acetonitrile were taken.
