Molecular chirality also affects the way in which self-assembly from chiral components occurs and the nature of the resulting supermolecular architecture. Three cases may be distinguished ... 

Oligopyridine liquid crystals as novel building blocks for supermolecular architectures based on metal coordination and hydrogen bonding 00AG(E)2454. 

However, the observed hysteresis supports a cooperativity effect. The hydrophobic lattice orients the magnetic polar heads, so that the neighboring molecules interact, and behave as supermolecular domains. It has been demonstrated that the spin transition is accompanied by a variation of the molecular volume in 3-D crystal experiments, and a mechanical coupling occurs. This coupling is clearly maintained in the LB films. Experiments towards purification and mechanism studies are in progress. But this supermolecular architecture opens the way for passive information storage at the molecular level.

In reffospect to Figure 7, there are essentially three types of supermolecular architectures (i) daisy chains of mesogens, (ii) mesogenic kiipooyaq, and (iii) giant snpermolecules... 

With the supermolecular architectures described in this section, it is difficult to continue adding more mesogens to the central scaffold in order to examine how the overall molecular shape changes, and thereby affects mesophase...

To a large extent low-dimensional solids represent by Aemselves supermolecular architectures m which slabs or fibers, Aat can be regarded as giant two- or one-dimensional molecules, are weakly bound togeAer to build a three dimensional arrangement. 

These are supermolecular architectures based on different connections of similar chains. Many other structures based on 3D arranged bicapped biprisms have been foimd in these series. However the most fascinating compound is Ta4P4S 9 (16).
