Enhanced Optical Limiting Effects in Porphyrin‐Covalently Functionalized Single‐Walled Carbon Nanotubes

Abstract

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 C60, the individual SWNTs, and porphyrins because of a combined nonlinear mechanism and photoinduced electron or energy transfer between the porphyrin moiety and the SWNTs.
