Effects of fullerene encapsulation on structure and photophysical properties of porphyrin-linked single-walled carbon nanotubes.

Fullerene-encapsulating single-walled carbon nanotubes (C(60)@SWNT) linked with porphyrins by a short bridge have been prepared for the first time. Steady state and time-resolved spectroscopies demonstrated the initial formation of an exciplex state, followed by a charge-separated state.
