“…Such a chemical shift to a shielding region is attributed to the ring current shielding effect among neighboring anthracene rings. Such an effect is observed in the 1 H NMR spectra of a series of 1,8-anthrylene-ethynylene cyclic tetramers as well as [2.2]anthracenophanes . In the 1 H NMR spectrum of 2A1X , signals of the anthracene units appeared at 6.9 ppm, whereas those of the inner anthracene ring in 3A2X appeared at around 6.5 ppm, as shown in Figure S21.…”

“…The dithia[2.2]-and tetrathia[2.2]cyclophanes 125 104 and 126 107 were both obtained as anti-stepped forms by straightforward preparative methods. 127 128 Molecular models of the circulene 128 indicate that the molecule has a saddle-shaped geometry and consequently would be dissymmetric and could potentially be resolved into enantiomers.…”

“…Isomer 137 could also be thermally isomerized to the anti form 136 (Scheme 12). 123 Cross-breeding reactions from the Hofmann degradation of quaternary ammonium hydroxides led to a number of related anthracenophanes, 126 including [2.2](l,4)(9,10)anthracenophane (139), 127 anti-and syn- 128 Dimethyl derivatives of compound 140 and [2.2]paracyclo(l,4)anthracenophane, together with the synthesis of a triple-layered 1,4-anthracenophane, have also been reported. 123 Cross-breeding reactions from the Hofmann degradation of quaternary ammonium hydroxides led to a number of related anthracenophanes, 126 including [2.2](l,4)(9,10)anthracenophane (139), 127 anti-and syn- 128 Dimethyl derivatives of compound 140 and [2.2]paracyclo(l,4)anthracenophane, together with the synthesis of a triple-layered 1,4-anthracenophane, have also been reported.…”

“…[2] Die Wechselwirkungen zwischen den einzelnen Anthracenchromophoren haben besondere Aufmerksamkeit erfahren und wurden mithilfe der Absorptions-und Fluoreszenzspektroskopie untersucht. B. in erweiterte orthogonale [1] wie auch in parallele p-Systeme, die bis zum Anthracen vergrçßert worden sind.…”

“…Die Arbeitsgruppe um Misumi hat auf diesem Gebiet durch die Synthese von Anthracenophanen wie 1 (Schema 1) in den 1970er Jahren signifikante Beiträge geliefert. [2] Die Wechselwirkungen zwischen den einzelnen Anthracenchromophoren haben besondere Aufmerksamkeit erfahren und wurden mithilfe der Absorptions-und Fluoreszenzspektroskopie untersucht. [3] Ihre Radikalanionen und -kationen wurden EPR-oder ENDOR-spektroskopisch studiert.…”
