Fluorescence Quenching of n,π-Excited Azoalkanes by Amines:  What Is a Sterically Hindered Amine?

The fluorescence quenching of two azoalkanes, the weak acceptor 2,3-diazabicyclo[2.2.2]oct-2-ene and its less reactive derivative 4-methyl-1-isopropyl-2,3-diazabicyclo[2.2.2]oct-2-ene, by a series of aliphatic amine donors was examined by time-resolved spectroscopy in benzene. The fluorescence quenc...
