Issue Date: | 2011 | Publisher: | CHEM SOC PAKISTAN | Source: | JOURNAL OF THE CHEMICAL SOCIETY OF PAKISTAN, 33 (3), p. 403-411 | Abstract: | A novel symmetric 3,4,9,10-perylenetetracarboxylic acid derivative (PDI1) dye based on thiophene donor group was synthesized and characterized by FT-IR and (1)H NMR. Cyclic Voltammetry analysis is performed to determine the energy levels of the perylene derivative. Optical characteristics were determined by visible absorption and fluorescence emission spectra. Spectral behavior and fluorescence quantum yield of PDI1 have been measured in different solvents. The dye exhibits high fluorescence quantum yield (Phi(f): 0.94-0.99). But the quantum yield PDI1 is very low in the n-butanol solution (Phi(f): 0.12). The photophysical properties have important implications for use in a variety of electroactive and photovoltaic applications. A photovoltaic device was fabricated with PDI1 as transporting material. The conversion efficiency for DSSC sensitized by PDI1 is 0.0065%. PDI1 exhibits electrochromic behavior by switching between neutral (red) and oxidized (blue) states. Electron transfer capacity of PDI to the TiO(2) was investigated by incorporation of dye as sensitizer in dye sensitized solar cell (DSSC). Soluble dye molecules are very important to prepare dye sensitized solar cell. Solubility was increased with thiophene group. | Notes: | [Hakli-Birel, Ozgul] Mugla Univ, Fac Art & Sci, Dept Chem, TR-48121 Mugla, Turkey.
