Boronic ester-substituted triphenylamines as new Lewis base-sensitive redox receptors

Three triphenylamines mono-, di-, and trisubstituted by boronic ester(s) ha ve been synthesized and their electrochemical behavior has been investigate d in the absence and in the presence of F- as a guest anion. New redox syst ems assigned to each complexed form were observed at less positive potentia ls as a result of the stabilization of the radical cation species. (C) 2000 Elsevier Science S.A.
