optical (NLO) phenomena may occur in materials which, when excited by
light impulses, undergo large changes in their molecular dipoles. Such
materials will also have large ground-state dipoles.
doubling is a one such NLO phenomenon. This means that light is
absorbed at a
given wavelength, and emitted at half of that wavelength.

phenomena from here.

are flat, dimeric structures formed by the self-assembly of
oligopyridine quinoxaline-type ligands with kinetically labile metal
ions, such as copper(I), silver(I) or cobalt(II) - see Equation 1.

object of this research is to synthesize important candidate molecules
verify the prediction of frequency doubling through work with yet other
dicopper(I) metallocyclophanes of compounds 4, 5 and 6 are three such candidate
molecules, and which we
have either recently prepared or are now preparing.
