Effect of water on the electron transfer dynamics of 9-anthracenecarboxylic acid bound to TiO2 nanoparticles: demonstration of the Marcus inverted region
Article Abstract:
The development of dye-sensitized semiconductor systems spawned scientific interest on factors affecting back electron transfer dynamics. Experiments were conducted to characterize the Marcus inverted region. The effects of water on the forward and back electron transfers in 9-anthracenecarboxylic acid (9AC) bound to titanium dioxide particles were also examined. The findings indicated a slight increase in back electron transfer reactions upon the addition of water and confirmed the Marcus inverted region as the site where high rates of this reaction occur.

Effect of structure on electron transfer reactions between anthracene dyes and TiO2 nanoparticles
Article Abstract:
A study was conducted to analyze the influence of structure on the electron transfer reactions between anthracene dyes and TiO2 nanoparticles. Controlled hydrolysis was carried in water of titanium(IV) isopropoxide to prepare anatase TiO2 nanoparticles. The Perkin-Elmer Lambda 6UV-vis spectrometer was then utilized to obtain steady-state absorption spectra. Results indicated that the preparation of the particles influenced the time constants for electron transfer for semiconductor particles-bound dye molecules.
