Study Data from University of Zanjan Provide New Insights into General Chemistry

June 4, 2014

By a News Reporter-Staff News Editor at Biotech Week -- Fresh data on General Chemistry are presented in a new report. According to news reporting from Zanjan, Iran, by NewsRx journalists, research stated, "Novel ruthenium multi carboxylic complexes (RMCCs) have been synthesized by using ruthenium nitrosyl nitrate, 1,2,4,5-benzenetetracarboxylic acid (H4btec) and 4,7-diphenyl-1,10-phenanthroline (BPhen) as photosensitizers for titanium dioxide semiconductor solar cells. The complexes were characterized by (1)H-NMR, FT-IR, UV-Vis, ICP and CHN analyses."

The news correspondents obtained a quote from the research from the University of Zanjan, "The reaction details and features were then described. SEM analysis revealed that the penetration of dyes into the pores of the nanocrystalline TiO2 surface was improved by increasing the number of btec units. The solar energy to electricity conversion efficiency of complexes shows that the number of attached carboxylates on a dye has an influence on the photoelectrochemical properties of the dye-sensitized electrode."

According to the news reporters, the research concluded: "An incident photon-to-current conversion efficiency (IPCE) of 13% at 510 nm was obtained for ruthenium complexes with three btec units."
