22. II coordination to a imine nitrogene site, but that it does indeed occur suffices for the present purposes. On addition of large amounts of zinc salt (up to 50 equiv), the DP decreases to about 5; however, the emission wavelength remains practically unchanged, indicating that the effect is not due to this factor.
