Molecular magnetic properties display

Ferrocene and some of its derivatives are well suited for the formation of CT complexes and offer an entry into solid state organometallic chemistry. Because such CT complexes contain radical species, the consideration of their physical properties is of fundamental importance and now constitutes an interdisciplinary research field. The systematic study of the magnetic properties of CT complexes of, notably, decamethylferrocene, by the Miller Epstein group has led to the discovery of bulk ferromagnetic molecular materials and to new insights into the mechanisms of magnetic coupling. Such results have shown that ID materials, as most CT complexes are, can display 3D properties if the molecular components are matched... 

These clusters display interesting magnetic properties, from ferromagnetic to antiferromagnetic couplings depending on the nature of the metal elements and the molecular structure. 

For some radicals the magnetic properties have been determined for different molecular environments or temperatures. In these cases the display of the data follows the following order solution (matrix), sin e crystal, polycrystalline, and for the same environment and different temperatures they are arranged according to increasing temperature. 

Development of new liquid crystalline (LC) polymeric materials has been a subject of intense interest because of the combination of unusual optical, electrical, and magnetic properties of low-molecular-weight liquid crystals and the mechanical performance and processibility of polymers. Application areas of LC polymers are very diverse, from engineering plastics to LC displays and erasable compact disks. However, the development of conducting and liquid crystalline polymers went on separately in the past in spite of the similarity of the molecular structures of typical main-chain liquid crystals and some conductive polymers.
