Organic Metals/Superconductors. These are based on buckminsterfullerene C60 and sulfur heterocycles. In the former, we have developed the chemistry of fulleroids and methanofullerenes (expanded fullerenes) as shown below for a series of .methanofullerenes:   This reaction was employed for the preparation of a derivative which inhibits various HIV (AIDS) virus enzymes. More recently we prepared a buckminsterfullerene with an orifice on its surface and the first azafullerenes C59HN and C69HN.

Organic Ferromagnets. Here we discovered the first organic ferromagnet based on C60. The material C60(TDAE) showed a transition to the ferromagnetic state at 16 K. We are also in the process of synthesizing molecules with triply degenerate LUMO orbitals, akin to the C60 LUMO level. Conjugated Polymers. In this project we prepared chiral and processable polymers with a conjugated backbone for the preparation of organic light emitting diodes (LED's). The polymers we prepared are: Where the chirality is derived from naturally occurring, optically active alcohols such as citronellol, etc. Specific rotations on the order of 3000 degrees were observed in the solid state, indicating that the conjugated polymer must be assuming a helical conformation. Polymers B (above) are being used for the development of very sensitive bioassays.
