Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1116-98-9, is researched, Molecular C7H11NO2, about Insight into the effects of the donors and pi-spacers on the photovoltaic performance of quinoline and pyridocarbazole based DSSCs, the main research direction is quinoline pyridocarbazole photovoltaic performance DSSC.Application of 1116-98-9.
Four novel D-π-A organic dyes containing quinoline (5a, 5b) and pyridocarbazole (5c, 5d) as the π-spacers have been synthesized for dye-sensitized solar cells (DSSCs). The exptl. and theor. results confirmed that the incorporation of pyridocarbazole in the dyes could be favorable for the long wavelength light-harvesting as compared to quinoline based dyes. Upon coadsorption with chenodeoxycholic acid (CDCA), the DSSC based on 5d exhibited the power conversion efficiency of 3.35%, which is better than those of 2.39%, 2.62% and 3.25% for 5a-c, resp. However, these efficiencies present only 8-15% of enhancement compared to that in the absence of coadsorbent, which suggests dyes 5a-d suppress the intermol. aggregation and restrain charge recombination. In other words, this work suggests that the introduction of quinoline or pyridocarbazole as the π-spacers into D-π-A organic dyes is a promising way for coadsorbent-free DSSCs.
