An isomeric pair of 15-membered dehydrobenzopyridannulenes functionalized with -NBu₂ groups asges/gifchars/pi.gif" BORDER=0 >-electron donors was prepared and their steady-state spectroscopic parameters investigated. The propertydifferences arising from placement of the pyridine nitrogen relative to the macrocycle, as well as thedifferential effects of stepwise protonation of the acceptor and donor nitrogens, were examined. Themacrocycles exhibited dynamic shifting in the emission spectra, which is believed to correlate to inducedchanges in the frontier molecular orbitals of the molecules.
