The electrochemical properties of DDiKTa-F and DiKTa were investigated using cyclic voltammetry (CV) and differential pulse voltammetry (DPV) in deaerated dichloromethane (DCM) with 0.1 M tetra-n-butylammonium hexafluorophosphate as supporting electrolyte (Figure ). The CV documents that the oxidation is irreversible while the reduction is a quasi-reversible process. The oxidation and reduction potentials, cm -1 ) due in part to its larger p-conjugation. The photoluminescence (PL) spectrum of DDiKTa-F in toluene, shown in Figure , has a peak maximum, lPL, of 476 nm, a shoulder at 511 nm, and a FWHM of 32 nm.
