PHENAZINE DERIVATIVE HAVING INCREASED SOLUBILITY, AND POLYMER FOR ORGANIC PHOTOVOLTAIC CONVERSION DEVICE, USING SAME

摘要

The present invention relates to a novel hole-transporting polymer and/or single molecule, a preparation method therefor, and an organic photovoltaic conversion device using the novel hole-transporting polymer as an active layer. According to the present invention, provided is a series of processes for preparing a hole-transporting polymer and/or single molecule having excellent photovoltaic conversion efficiency, having enhanced absorbance properties including the absorbance of long wavelengths by having a heterocyclic compound introduced thereto, and having charge transfer properties by the effective transfer of electrons by effective intermolecular stacking. In addition, an organic photovoltaic conversion device using the novel hole-transporting polymer as a photoactive layer is provided, and thus an effect is achieved whereby the organic photovoltaic conversion device may be usefully employed as a next-generation organic photovoltaic conversion device exhibiting stable photovoltaic conversion efficiency and having excellent conversion efficiency.
