Abstract

In this review, we attempt to present the most notable aspects of the story of the two chain, highly one-dimensional, organic conductors of the perylene metal-dithiolate series, which have been under investigation since the end of the 1960's until the present time, with the recent discovery of a superconducting phase. We will start with an overview of the developments of the research on this materials and then, after a brief introduction and a survey of the theoretical background, we will describe and discuss the structure, transport and magnetic properties, as well as the low temperature instabilities and phase transitions. Finally we will focus on the study of their behaviour under extreme conditions of low temperatures, high pressures and high magnetic fields up to 45 tesla.
