NOVEL VINYL-TYPE POLYNORBORNENES WITH PENDANT FULLERENE GROUPS, PREPARATION METHOD THEREOF AND ORGANIC SOLAR CELLS COMPRISING THE SAME

摘要

PURPOSE: A fullerene-containing vinyl-based polynorbornene polymer is well dissolved in organic solvent, has high heat resistance, has excellent photoelectric conversion efficiency when manufactured to an organic solar cell, and can use a wet process. CONSTITUTION: A fullerene-containing polynorbornene polymer is represented by chemical formula 1. A manufacturing method of the polynorbornene polymer includes a step of manufacturing a norbornene monomer including a fluorene group as a side chain by the reaction of 5-norbornene-2-alkyl alcohol and an acid including fullerene under the presence of an organic solvent; and a step of manufacturing a polynorbornene polymer by polymerizing M1 through a vinyl addition polymerization using a palladium catalyst.
