Fullerenes bound to an insoluble polymeric phase: surface photophysical studies using diffuse reflectance laser flash photolysis (DRLFP)

Fullerenes C 60 and C 70 were covalently bound to an insoluble cross-linked (2% divinylbenzene (DVB)) polystyrene. The transient absorption of the polymeric C 60 triplet was recorded by diffuse reflectance laser flash photolysis (DRLFP) showing a lifetime similar to that described for the C 60 tripl...

More Information
Summary:Fullerenes C 60 and C 70 were covalently bound to an insoluble cross-linked (2% divinylbenzene (DVB)) polystyrene. The transient absorption of the polymeric C 60 triplet was recorded by diffuse reflectance laser flash photolysis (DRLFP) showing a lifetime similar to that described for the C 60 triplet dissolved in toluene. The deactivation by molecular OZ has a quenching constant two orders of magnitude smaller than in solution.
