9 Molecular Flexibility and Material Properties
There remains plenty of issues to be investigated further. One concerns the role of
the effective molecular form on molecular dynamics such as diffusion and reorientation. The dependence of anisotropy of self-diffusion [98] may be clarified by taking
the molecular form into account. The dynamics in neighboring phases are interesting
from the viewpoint of the relation between molecular form and aggregation states.
Another issue is the applicability of the discussed idea in non-orthogonal smectic
phases, such as the SmC phase, in which the cores cooperatively incline in one direction. The investigation of SmC phases would be valuable to clarify such points as
what in reality incline in non-orthogonal phases, whether the core is normal to the
layer in orthogonal phases, or what causes the averaged inclination of the disordered
alkyl chain.
