Abstract 

Superconductors and magnets in which the electronically-active components are molecules rather than atoms often consist of π-electron open-shell molecular units as the main component of the electronic conduction and spin network, respectively. Current best-in-class materials are the all-carbon π-electron fullerides–these show the highest known superconducting critical temperature, Tc at 38 K coupled with a record upper critical magnetic field, Hc2 in excess of 90 T. The dominance of strong electron correlations in defining their behavior poses significant challenges for understanding the highly robust superconducting response to both temperature and magnetic field in these highly correlated molecular systems. In addition, we have recently unveiled other extended molecular carbon-based π-systems such as ionic polyaromatic hydrocarbons (PAHs) as new electronic materials platforms beyond C60–here alkali metal phenacenes have provided the first example of a 3D quantum spin-liquid state to 50 mK arising purely from π-electrons, while at the same time harboring orbitally entangled states, prerequisites of the emergence of quantum magnetism and exotic superconductivity. Here I will attempt to trace the development of this field of science to date with emphasis on its current status and future prospects.
