Two new organic dye-sensitized solar cell (DSSC) sensitizers bearing regioisomeric carboxyl-N-methylpyridinium moieties were prepared and fully characterized. Based on TD-DFT calculations, they were anticipated to show a significantly red-shifted absorption spectrum compared to normal carboxypyridines and other regioisomeric pyridinium salts. Although this prediction was met, the two regioisomers unexpectedly showed very different stabilities upon adsorption on TiO2.

Abstract
Two new organic dye-sensitized solar cell (DSSC) sensitizers bearing regioisomeric carboxyl-N-methylpyridinium moieties were prepared and fully characterized. Based on TD-DFT calculations, they were anticipated to show a significantly red-shifted absorption spectrum compared to normal carboxypyridines and other regioisomeric pyridinium salts. Although this prediction was met, the two regioisomers unexpectedly showed very different stabilities upon adsorption on TiO2.File in questo prodotto:
