摘要

The electrochemistry of [Cu(OEP)] and [Ni(OEP)] are compared with the mixed-valence π-cations me="mml9">method=retrieve&_udi=B6TG5-4MMWHM4-1&_mathId=mml9&_user=1067359&_cdi=5245&_rdoc=19&_acct=C000050221&_version=1&_userid=10&md5=8a1161beca80d0c62c876671090e82c8">mg src="http://www.sciencedirect.com/cache/MiamiImageURL/B6TG5-4MMWHM4-1-1D/0?wchp=dGLbVzz-zSkzV" alt="View the MathML source" title="View the MathML source" align="absbottom" border="0" height=22 width="104"/> and me="mml10">method=retrieve&_udi=B6TG5-4MMWHM4-1&_mathId=mml10&_user=1067359&_cdi=5245&_rdoc=19&_acct=C000050221&_version=1&_userid=10&md5=2601a895ccae2db323e30b86638a18c6">mg src="http://www.sciencedirect.com/cache/MiamiImageURL/B6TG5-4MMWHM4-1-K/0?wchp=dGLbVzz-zSkzV" alt="View the MathML source" title="View the MathML source" align="absbottom" border="0" height=21 width="101"/>. These electrochemical studies, carried out with cyclic voltammetry and hydrodynamic voltammetry, show that the mixed valence π-cations have distinct electrochemical properties, although the differences between the [M(OEP)]^+/0 and me="mml11">method=retrieve&_udi=B6TG5-4MMWHM4-1&_mathId=mml11&_user=1067359&_cdi=5245&_rdoc=19&_acct=C000050221&_version=1&_userid=10&md5=6607817aa36f97b1a03ec1630210e4e7">mg src="http://www.sciencedirect.com/cache/MiamiImageURL/B6TG5-4MMWHM4-1-M/0?wchp=dGLbVzz-zSkzV" alt="View the MathML source" title="View the MathML source" align="absbottom" border="0" height=22 width="112"/> processes are subtle.
