|Title:||Synthesis Of C 60-containing Polymers By Ring-opening Metathesis Co-polymerization Of A C 60-cyclopentadiene Cycloadduct And N-(cycloheptyl)-endo-norbornene-5, 6-dicarboximide And Their Application In A Photovoltaic Device|
Van Otterlo W.A.L.
|Abstract:||A C 60-cyclopentadiene cycloadduct and N-(cycloheptyl)-endo- norbornene-5,6- dicarboximide were utilized as co-monomers in ring-opening metathesis polymerization (ROMP) reactions to afford a series of polymers containing C 60 in varying ratios. The polymerization reactions were catalyzed by the Grubbs second-generation ruthenium catalyst, and the co-polymers formed were investigated by spectroscopic and thermal techniques. The photovoltaic behavior of the new materials was studied by the construction of a simple sandwich-type photovoltaic cell. Under irradiation we concluded that the C 60 in the copolymers simultaneously accelerated both the charge separation in the polymer and the charge recombination between the electrons in the TiO2 and the electrolyte.
