Abstract
In this work, the compound 10-[(4-cyanobenzylidene)]-anthracen-9(10H)-one (1) has been synthesized from the corresponding anthrone and 4-cyanobenzaldehyde. It has been characterized by nuclear magnetic resonance (NMR), infrared spectroscopy (IR), high-resolution mass spectroscopy (HRMS) and single-crystal X-ray diffraction (XRD) analysis. Moreover, square wave voltammetry (SWV) was performed to determine the HOMO and LUMO potential levels of the anthrone derivative 1, which indicates that sensitization of TiO2-based electrodes is thermodynamically feasible. Therefore, this characteristic of compound 1 allowed its incorporation in a Grätzel-type solar cell. Photocurrent density measurements under UV irradiation are proportional to the light source intensity, and the operational parameters of the photoelectrochemical cell are relatively stable over time. In fact, the sensitivity of the generated photocurrent normalized by the supplied irradiance for TiO2-1 (7.73 µA/mW) as a photoanode is higher than that of TiO2 alone (5.14 µA/mW), indicating the improvement that 1 provides to TiO2 with respect to UV light detection. The higher photocurrent and the improved stability due to the implementation of 1 are very promising for possible applications as a sensitizer for UV light intensity sensors in dye-sensitized solar cells (DSSC).
