π-electron donors was prepared and their steady-state spectroscopic parameters investigated. The property
differences arising from placement of the pyridine nitrogen relative to the macrocycle, as well as the
differential effects of stepwise protonation of the acceptor and donor nitrogens, were examined. The
macrocycles exhibited dynamic shifting in the emission spectra, which is believed to correlate to induced
changes in the frontier molecular orbitals of the molecules.
