Our group is looking to synthesize new donor-linker-acceptor (D-p-A) compounds for dye-sensitized solar cell (DSSC) application. In our previous experiment, commercially available trans-p-methoxycinnamaldehyde was used to synthesize 2-cyano-5-(4-methoxyphenyl)-penta-2,4-dienoic acid compound. In this experiment, we have successfully synthesized a new starting compound, 5-(4-methoxyphenyl)-2,4-pentadienal, via the Wittig reaction. The desired product was characterized via 13C, 13C DEPT, and 1H NMR spectroscopy methods. The 13C NMR analysis showed the aldehyde peak at 193.56 ppm and all the other characteristic peaks of our product with an extra unit of p-conjugation in the linker section. Furthermore, UV-Vis spectral analysis of our reactant and product showed a red shift of lmax for our desired product.
