Abstract
Eine starke Excitonkopplung, die zur Aufspaltung der Soret‐Bande führt, und nur geringe spektroskopische Änderungen bezüglich der Q‐Bande deuten auf die senkrechte Anordnung der beiden Porphyrinringe im Dimer 1 hin. Diese Verbindung sowie die analogen linearen Tri‐ und Tetramere entstehen durch oxidative Kupplung des entsprechenden 5,15‐Diarylporphyrins und sind die ersten Beispiele für Verbindungen mit direkt meso‐meso‐verknüpften Porphyrin‐Chromophoren. Ar = 3,5‐tBu2C6H3. magnified imageKeywords
