Areas of Research/Interest
Synthesis of new types of fullerene derivatives; synthesis of porphyrin-fullerene dyads with flexible and rigid linkers; photoadditions to C60 and C70; photophysical studies of porphyrin-fullerene dyads; topological control of electron transfer and energy transfer in porphyrin-fullerene dyads; sensitization of singlet oxygen formation by fullerenes; fullerene derivatives as inhibitors of HIV-protease and in photodynamic therapy

Research Description
Current research in the Schuster lab at NYU centers on the synthesis of nanoscale electron donor-acceptor systems with potential applications in solar energy storage devices, in which porphyrin and C60 moieties are covalently or mechanically linked, as in rotaxanes and catenanes. Study of their electrochemical and photophysical properties is carried out with outside collaborators. Photoexcitation of these materials in polar organic solvents results in extremely fast electron transfer on the subnanosecond time scale to yield relatively long-lived charge separated radical ion pair (CSRP) states. CSRP lifetimes of microseconds have been achieved, and even longer lifetimes are anticipated for systems currently under study. Other work involves synthesis of fullerene derivatives which are expected to act as inhibitors of HIV protease. Since Professor Schuster no longer accepts doctoral students, work is currently carried out by undergraduate research students and postdoctoral fellows.
