Abstract

Currently, the reagents in most solar panel chemical reactions are materials like water that are readily available on earth’s surface. But what if less obvious, but potentially more efficient reagents, existed? The objective of this research was to demonstrate the possibility of electrochemically inducing dimerization of 2-methylthiophene to generate 5,5’-dimethyl-2,2’- bithiophene (i.g. the 2-methylthiophene dimer).

Through the formation of this bond, energy can be stored and released for use in a solar panel. The dimerization of 2-methylthiophene in the presence of a Pd2+ catalyst and atmospheric molecular oxygen was confirmed; in the absence of molecular oxygen, no dimerization product was observed. The data suggests the possibility of an ionic strength dependence for the yield of 5,5’-dimethyl-2,2’-bithiophene. The formation of 5,5’-dimethyl-2,2’-bithiophene was not observed during the electrochemical oxidation of 2-methylthiophene under any conditions studied. Further research is necessary to determine under what deoxygenated conditions 2-methylthiophene will dimerize.
