It should also be noted that the stability of the distinct mesophases can be quite different. It seems that there is a significant effect of molecular shape and topology, stabilizing SmA phases in the system 41/43 and Colhex phases in the system 35/37. In addition, the mesophase stability is often reduced close to the transition to another mesophase (see Fig. 15). Hence, the order-disorder temperatures can only be roughly estimated based on segmental solubility parameters [24, 25].

We have seen the importance of the self-assembly of coordination chains with their neighbors to control not only the dimensionality of the resulting network but also its topology, stability, and properties. This concept is even more crucial in multistrand helices, where each strand interweaves with the other. Thus, in many cases, the formation and stabilization of these supramolecular systems are closely related to the presence of hydrogen bonds. A representative example of a simple double-stranded helical system stabilized by hydrogen bonds has been reported by Chen et al. The simplest unit in [Co(L3i)(phen)(H20)2] consists of a helical chain created by the connection of...
