Figure 5
(a) View of the π–π stacking interaction observed for one of the phenylene groups of the anthracene fragments and (b) a view of the same, perpendicular to the planes of the anthracenyl (C21—C34) fragments [symmetry code: (i) 2 − x, 1 − y, 1 − z]. Other occurrences of parallel (but not stacked) anthracenyl units are shown in Figs. S1, S2 and S4. |
