Hydroxyethyl and ester co-functionalized imidazolium iodide for highly efficient solid-state dye-sensitized solar cells
Li, Juan,Wang, Hong,Zhou, Gang,Wang, Zhong-Sheng
, p. 9446 - 9448 (2013)
Hydroxyethyl and ester co-functionalized imidazolium iodide has been designed and synthesized as an efficient solid state electrolyte for dye-sensitized solar cells. Single crystal X-ray analyses confirm the presence of ordered three dimensional ionic channels for iodide, which exhibits high conductivity when mixed with iodine and LiI and achieves a power conversion efficiency of 7.45%.

We have successfully synthesized imidazole-dye conjugates by linking imidazole and nitroimidazoleacetic acids to an indocyanine green (ICG) carboxylic acid derivative, using an ethanolamine linker. These dye-conjugates show absorbance peaks at 754-756 nm and fluorescence peaks at 780 nm. The dye-conjugates show a blue shift of 25 nm and 30 nm in the absorption and fluorescence spectra respectively when compared to that of standard cardiogreen. There is no change in absorption and fluorescence spectral profiles between the ICG derivative and imidazole conjugates. The extinction coefficients of new ICG derivative and imidazole conjugates are 1.8 times higher than that of standard ICG. The relative quantum yields of the new compounds are 4.5-5.5 times higher than that of the Sigma-Aldrich's ICG. The dyes are tested for hypoxia in-vitro with 4T1 luc cell lines and it is found that the cells treated with 2-nitroimidazole ICG show a contrast of fluorescence signal of 2.5-3.0 for the cells under hypoxic to that of cells under normoxic. However pure ICG shows no significant difference between hypoxic and normoxic cells.

N-alkylation of N-trimethylsilylimidazole
Lebedev,Sheludyakov,Lebedeva,Frolov,Shatunov,Ustinova,Kovaleva
, p. 1086 - 1088 (2008/03/11)
The reaction of N-trimethylsilylimidazole with alkyl chloroacetates is studied. This process yields a mixture of N-alkylation and quarternization products in the ratio dependent on the reaction conditions. The reaction mechanism is discussed. 1H NMR data show that high melting point and low solubility of 1-imidazolylacetic acid in organic solvents are evidently caused by the formation of strong intermolecular hydrogen bonds, whereas in water zwitterionic structures with the protonation of both nitrogen atoms are formed.
