Abstract: 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. Electrochem. 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.Ethyl propiolate(cas: 623-47-2Safety of Ethyl propiolate) was used in this study.
Ethyl propiolate(cas: 623-47-2) is a clear colorless to pale yellow liquid that is soluble in ethanol, ether and chloroform. It an important organic chemical raw material and pharmaceutical intermediate. Ethyl propargylate is obtained by oxidation of propargyl alcohol to propargylic acid followed by esterification.Safety of Ethyl propiolate
