On a class of organic superconductors: A summary of findings

It was found experimentally that six compounds of the homologous cholates and their acids exhibit a new kind of superconductivity not hitherto seen in the superconducting metals or alloys. This superconductivity is manifested in a two-phase state, with the superconducting state occurring in small randomly dispersed domains side by side with the bulk insulating state in which the superconducting domains are sparsely dispersed. The transition temperature of these compounds ranged from 7.5 K for the sodium dioxycholate to 277 K for the sodium cholanate.
