Abstract
L'invention concerne la préparation d'un
sel de cation radicalaire de formule :
(Ar)₂.⁺ X⁻
dans laquelle Ar est un hydrocarbure aromatique éventuellement
substitué et X⁻ est un anion choisi parmi AsF₆⁻
, SbF₆⁻, ClO₄⁻, Pf₆⁻, BF₄⁻ et ((BC₆H₅)₄) par réaction
électrochimique d'une solution de Ar dans un solvant
organique avec un sel d'ammonium quaternaire
comportant l'anion X⁻. Le solvant organique est
un formiate d'alkyle tel que le formiate de méthyle
ou d'éthyle. The invention relates to the preparation of a radical cation salt of formula:
(Ar) ₂ . ⁺ X⁻
in which Ar is an optionally substituted aromatic hydrocarbon and X⁻ is an anion chosen from AsF₆⁻, SbF₆⁻, ClO₄⁻, Pf₆⁻, BF₄⁻ and ((BC₆H₅) ₄) by electrochemical reaction of a solution of Ar in a solvent organic with a quaternary ammonium salt comprising the anion X⁻. The organic solvent is an alkyl formate such as methyl or ethyl formate.
Le sel de cation radicalaire peut être utilisé dans un magnétomètre à résonance paramagnéti que électronique (RPE) qui comprend un tube (21) contenant ce sel (27) et un matériau capable d'absor ber l'eau constitué par exemple par des particules de tamis moléculaires (23) mélangées à de la poudre d'alumine (25). The radical cation salt can be used in a paramagnet resonance magnetometer electronic (RPE) which includes a tube (21) containing this salt (27) and a material capable of absorbing ber water constituted for example by particles molecular sieves (23) mixed with powder alumina (25).
