Mr Egmont Rohwer (Stellenbosch University)


Various derivatives of a zinc phthalocyanine molecule, covalently linked or adsorbed to the surface of carbon nanotubes, are excited at their respective absorption bands to subsequently monitor transmission changes with a delayed probe pulse. The aim is to identify charge separated states, their lifetimes and the pathway of the induced photoreaction.
