Abstract

original image

Nicht aus der Reihe tanzen: Ein unsubstituiertes N-invertiertes Metalloporphyrin bildet in Lösung sowohl C3- als auch C1-symmetrische Trimere, das monophenylsubstituierte Analogon dagegen liegt ausschließlich als C3-symmetrisches Trimer vor (siehe Bild). Der sowohl experimentell als auch theoretisch nachgewiesene Grund sind deutliche stabilisierende nichtkovalente Wechselwirkungen zwischen den drei Phenylgruppen.
