Despite the predominant electron donor character of p-phenylenediamine, our studies on extended p-phenylenediamine derivatives show that they can not only be chemically oxidized, giving well-known Wurster-type radical cations, but also be chemically reduced, giving radical anions. Making use of EPR/ENDOR spectroscopy and supported by DFT calculations, we(More)
The photophysics of two molecular wire building blocks of different lengths based on p-phenyleneethylene, namely, 1,4-bis[p-(N,N-dimethylamino)phenyl]-1,2-ethyne and 1,4-bis[p-(N,N-dihexylamino)phenylethynyl]benzene, are studied experimentally in a wide range of organic solvents. The band shape and position of the electronic absorption and fluorescence(More)
