Dimensionality and Electrical Properties in Organic Synthetic Metals-Current Results through Selected Recent Examples

In this article on synthetic metals and organic superconductors, we recall, from the literature data, how an increase in dimensionality appeared to be a key element to stabilize the metallic character of TTF-based materials and to possibly increase Tc in superconducting salts. We then reviewed, through the main trends currently developed, the results obtained during the last decade in the search for new salts and complexes that might display a higher dimensionality associated with a higher electrical conductivity. Typical examples taken from the recent literature are given to illustrate the most interesting findings to date.
