Abstract:

Following the discovery of C60 (a quasi-spherical molecule with 
dimensions of ~1 nm) in 1985, the subsequent isolation and preparation 
of bulk crystalline samples of fullerenes—a set of hollow, closed-cage 
molecules consisting purely of carbon—from arc-processed carbon in 1990 
sparked off a remarkable interdisciplinary research activity, 
encompassing diverse fields of chemistry, physics and materials science. 
The early research activity quickly culminated in 1991 in the synthesis 
of superconductors with stoichiometry A3C60 (A = alkali metal) and 
considerably enhanced superconducting transition temperatures, Tc, when 
compared with any other molecular system. This was followed by a long 
period during which the established fulleride chemistry failed to 
deliver new materials. Therefore the physical picture of fullerene 
superconductivity remained unaltered until 2008 when the discovery of 
Cs3C60 led to their rebirth and demonstrated their commonality with 
other classes of unconventional superconductors such as the cuprates and 
the iron chalcogenide/pnictide systems. Here I will attempt to trace the 
development of this field of science to date with emphasis on its 
current status and future prospects
