Such PC\u2010bridged MV systems are important intra\u2010molecular model systems for inter\u2010molecular electron transfer (ET) via \u03c0\u2010stacked aromatics, since they allow enforcement of a more or less well\u2010defined geometrical arrangement. Closely comparable ET barriers and electronic couplings for all [2.2] and [3.3] bridges are found for these class\u2010II MV systems, irrespective of the use of pseudo<\/jats:italic>\u2010para<\/jats:italic> and pseudo<\/jats:italic>\u2010meta<\/jats:italic> connections. While the latter observation contradicts notions of quantum interference for off\u2010resonant conduction through molecular wires, it agrees with the less intricate nodal structures of the highest occupied molecular orbitals. The ET in such MV systems may be more closely connected with hole conduction in the resonant regime. Computations on model cations, in which the [2.2] linkers have been truncated, confirm predominant through\u2010space \u03c0\u2010\u03c0 electronic coupling. Systems with [4.4] PC bridges exhibit far more structural flexibility and concomitantly weaker electronic interactions between the redox centers. \u00a9 2015 Wiley Periodicals, Inc.<\/jats:p>","DOI":"10.1002\/jcc.24038","type":"journal-article","created":{"date-parts":[[2015,8,12]],"date-time":"2015-08-12T05:29:24Z","timestamp":1439357364000},"page":"93-102","source":"Crossref","is-referenced-by-count":16,"title":["Electron transfer pathways in mixed\u2010valence paracyclophane\u2010bridged bis\u2010triarylamine radical cations"],"prefix":"10.1002","volume":"37","author":[{"given":"Martin","family":"Kaupp","sequence":"first","affiliation":[{"name":"Technische Universit\u00e4t Berlin Institut f\u00fcr Chemie, Theoretische Chemie\/Quantenchemie, Sekr.
