Abstract:Crystal structures of three bisazomethine dyes with dipropyl, dibutyl, and dihexyl substituents on their terminal amino groups are reported. To systematically interpret the effects of the terminal dialkyl substituents on the low-dimensional arrangements of the π–π stacked molecules, the structural features of the molecular geometries and the low-dimensional arrangements were compared with those in the reported crystal structure of two bisazomethine dyes, i.e. with terminal dimethylamino and diethylamino groups… Show more
“…Unusual bond lengths associated with the terminal diethylamino groups were observed for both molecules A and B. 34 The least squares planes of the conjugated system of DE2 for A and B were not parallel to each other, and instead were stacked with a tilt angle of 23.7° ( Fig. S1b, ESI †).…”
