    Description / Table of Contents: Electron Donor-Acceptor Compounds, XXXI. Electron Donor-Acceptor [3.3]Paracyclophanes with N,N,N′,N′-Tetramethyl-p-phenylenediamine (TMPD) as Donor UnitThe electron donor-acceptor [3.3]paracyclophanes 1 and 2 which contain the combination of N,N,N′,N′-tetramethyl-p-phenylenediamine and p-benzoquinone were synthesized starting from 3 and 4 via 5, 7, 9, 11, 13 and 6, 8, 10, 12, 14, respectively. Charge transfer(CT) absorptions of the pair of isomers 1 and 2 differ considerably as a consequence of the orientation dependence of CT transitions. Based on an X-ray structure analysis, special features of the molecular and crystal structure of 2 are discussed.
    Notes: Die Elektron-Donor-Acceptor-[3.3]Paracyclophane 1 und 2, die die Kombination N,N,N′,N′-Tetramethyl-p-phenylendiamin und p-Benzochinon enthalten, wurden ausgehend von 3 und 4 über 5, 7, 9, 11 und 13 bzw. 6, 8, 10, 12 und 14 synthetisiert. Die Charge-Transfer(CT)-Absorptionen des Isomerenpaars 1 und 2 zeigen als Folge der Orientierungsabhängigkeit des CT-Übergangs beträchtliche Unterschiede. Die Molekülstruktur und Gitterpackung von 2 werden anhand einer Röntgenstrukturanalyse diskutiert.
