ABSTRACT
For many years, there has been speculation that organic materials might provide a possible route to high temperature superconductivity. Carbon is a most “talented” atom, which takes a leading role in many molecular productions including life itself. As a free atom, it has four electrons in its outer shell: just half the number needed to fill that shell. In forming compounds it shares these four electrons with other electron-sharing atoms, which can, and often do, include carbon itself, to make covalent bonds. In combination with nitrogen, oxygen, hydrogen, phosphorus or other carbon atoms, carbon can be built up into an almost limitless variety of molecules comprised of chains, branched chains, sheets and composites of these. Some of these organic compounds are superconductors.
