| Abstract: | New donor-acceptor dyads containing tetrathiafulvalene (TTF) and 2,5-diphenyl-1,3,4-oxadiazole (PPD) moieties were synthesized to develop new photoconducting materials. Crystal structure analysis indicated the highly planar molecular skeleton of the dyad. Fluorescence from the PPD part was almost quenched by the intramolecular electron transfer from the TTF part to the PPD part. Photoelectrochemical measurements indicate that cathodic photocurrents can be generated from a thin film of the dyad spin-coated on ITO electrode. |
