Electron-transfer fluorescence quenching by aliphatic amines

Abstract

Electron-transfer interaction of an excited aromatic molecule with an aliphatic tertiary amine leads to a pattern of intermediate products not to be expected from earlier work with aromatic amines. The reasons for this phenomenon are briefly discussed.

Fluorescence quenching of 8-methyl quinolinium: An efficient halide indicator mechanism

“…A variety of substances can act as quenchers. Some common examples are molecular oxygen [3][4], amines [5][6][7][8][9], metal ions [10,11] and halides [12][13][14][15][16][17][18].…”
