The synthesis and characterization of quinone dimers connected by 1,4-phenylene (QPQ) and 2,5-thienylene (QTQ) linkers are described. QPQ and QTQ were synthesized by means of Suzuki coupling and subsequent oxidation. Significant bathochromic shifts were observed in the electronic absorption spectra of QPQ and QTQ as compared to that of the quinine dimers without a linker. In addition, cyclic voltammetry and DFT calculations demonstrated that QTQ was a stronger electron acceptor than QPQ due to its planar structure, even though QTQ contains an electron-rich thiophene ring.
