Single‐walled carbon nanotubes covalently functionalized with porphyrins present enhanced optical limiting effects. Both porphyrins and SWNTs are good candidates for optical limiting applications. The porphyrin‐covalently functionalized SWNTs offer superior performance to C 60 , the individual SWNTs, and porphyrins because of a combined nonlinear mechanism and photoinduced electron or energy transfer between the porphyrin moiety and the SWNTs.
