One and two-photon matrix photoionization techniques have been used to prepare diphenylacetylene and 1,4-diphenylbutadiyne cations. Identification of these cations was confirmed by photoelectron spectra and radiolysis studies. Near-infrared absorption bands for each cation correlate with photoelectron spectra and suggest structural relaxation about the molecular axis on ionization, and strong blue absorptions that do not correlate with photoelectron spectra are probably caused by π → π* transitions.
