indicative of the flexibility of the scaffold, which allows for a wide variety of
conformers to be present in the lower generations that support the formation
of rod-like gross shapes of the supermolecule (see Donnio and Guillon for
a very detailed review of liquid-crystalline dendrimers and polypedes [76]).
2.1
Effect of Density of Mesogens and Number Generation
The reports by Elsäßer et al. concerning the formation of carbosilazane-based
multipedal systems provides for one systematic study where material de-
sign and preparation was taken from a simple bimesogen to trimesogen and
through to dendrimer. In addition, the soft-centered core was changed in gen-
eration number from 0 to 2, where mesogens were appended laterally to the
