Experimental study demonstrates 5.12–6.59% photovoltaic efficiency in novel pyrido-pyrazoloquinolines, suggesting their utility in dye-sensitized solar cells.
New fluorescent heterocyclic compounds pyrido[1',2':1,5]pyrazolo[4,3-b]quinolines have been synthesized by the reaction of 3-nitropyrazolo[1,5-a]pyridine with different arylacetonitriles in high yield. Structural assignments of the new compounds are based on their spectral data. The study of optical properties of the compounds has revealed their high fluorescence quantum yields. Electrochemical properties of the compounds have been studied by cyclic voltammetry. The IPCE spectra and the I–V curves of the florescence compounds have been obtained, and their photovoltaic performance of 5.12–6.59 % has been achieved.
