Aluminum tris-(8-hydroxy quinoline) forms thin amorphous films with favorable semiconducting properties. In view of future studies of the structure and dynamics of such films, we have undertaken a systematic 2D exchange NMR study of the intrinsic ligand exchange dynamics of Alq3 in solution. The exchange follows first order kinetics, and the results can be explained quantitatively in terms of a simple model based on 180 deg. flips of the ligands.
