Organische Leiter

Only three decades ago it was thought inconceivable that organic compounds could transport electric charges like metals do. However, recently organic molecules exhibiting high conductivities have been synthesized. Some examples of organic conductors are presented together with the present status of this research which is both interesting to chemists and physicists. Some applications of organic conductors are discussed.     

Unusual ring systems in organic chemistry

The Science of Nature - In this article several compounds with unusual ring systems are surveyed briefly. Saturated and unsaturated monocyclic compounds, polycyclic compounds, and unconventional...
