AB  - Single-wall carbon nanotube (SWNT) field effect transistors (FETs), 
      functionalized noncovalently with a zinc porphyrin derivative, were used to 
      directly detect a photoinduced electron transfer (PET) within a donor/acceptor 
      (D/A) system. We report here that the SWNTs act as the electron donor and the 
      porphyrin molecules as the electron acceptor. The magnitude of the PET was 
      measured to be a function of both the wavelength and intensity of applied light, 
      with a maximum value of 0.37 electrons per porphyrin for light at 420 nm and 100 
      W/m2. A complete understanding of the photophysics of this D/A system is 
      necessary, as it may form the basis for applications in artificial photosynthesis 
      and alternative energy sources such as solar cells.
