Molecular nanowires

In contrast to organic liquid crystals, mineral liquid crystals can differ largely in size from one system to another. They actually range from molecular nanowires or nanotubes to anisotropic crystallites such as nanorods. Molecular nanowires can be considered as one-dimensional objects where the diameter is precisely defined by the molecular unit that makes up the chain (typically...

In general, nanotechnology MBBs are distinguished for their unique properties. They include, for example, graphite, fullerene molecules made of various numbers of carbon atoms (C60, C70, C76, C240, etc.), carbon nanotubes, nanowires, nanocrystals, amino acids, and diamondoids [97]. All these molecular building blocks are candidates for various applications in nanotechnology. 

Attention has been given to the synthesis of bimetallic silver-gold clusters [71] due to their effective catalytic properties, resistance to poisoning, and selectivity [72]. Recently molecular materials with gold and silver nanoclusters and nanowires have been synthesized. These materials are considered to be good candidates for electronic nanodevices and biosensors [73].

It is important to point out that if plating is terminated before solid Au nanowires are obtained, Au nanotubules that span the complete thickness of the template membrane are deposited within the pores. We have shown that these nanotubule membranes have interesting ion [71] and molecular [72] transport properties. This will be subject of the following section.
