5 Patterns of ZL Crystals
Hierarchically organized structures, presenting successive ordering from the molecular up to mm or cm scale, are of great interest. They allow establishing direct
relationship between the molecular arrangements and the macroscopic properties. A
high degree of supramolecular organization is important in device chemistry, for
attaining the desired macroscopic qualities. Possibilities for achieving such organization are the self-assembly of the zeolite crystals into oriented structures, the
embodiment into nanofibers, contact with biological objects, solubilization in polymer matrices, and the preparation of mono-directional materials. Self-assembly can
be guided by applying stopcock functionalization of ZL crystals that may contain
different kind of guests. The beauty of this approach is that single building blocks
can be connected in such a way that they can keep their individual properties but in
addition, through controlled assembly, generate new functions not present in the
Fig. 11 Two principles for obtaining surface modification. (a) Modification of stopcock-modified
composites where the stopcocks have no affinity to the modifying reagent. (b) Sealing the channel
entrances and modification of the coat using the same reagent
