Molar absorption coefficient and radiolytic yield of solvated electrons in diethylmethyl(2-methoxy)ammonium bis (trifluoromethanesulfonyl)imide ionic liquid

The molar absorption coefficient and the radiolytic yield of solvated electron in ionic liquid of DEMMA–TFSI were estimated respectively to be 2.3×104 L mol−1 cm−1 and 0.8×10−7 mol J−1 by observing the reaction and kinetics of solvated electron and dry electron in the ionic liquid. The solvated electron in DEMMA–TFSI has a very broad absorption spectrum peaking at 1100 nm and reacts slowly with pyrene with a rate constant of 3.5×108 L mol−1 s−1, while the dry electron is captured rapidly by pyrene with C37 value of 0.065 mol L−1.
