Adiabatic electron affinities (EA a's) of seven oligophenyls: biphenyl (BP), 4-cyanobiphenyl (CNBP), o-terphenyl (o-TP), m-terphenyl (m-TP), p-terphenyl (p-TP), p-quaterphenyl (p-QP), and 1,3,5-triphenylbenzene (TPB), have been evaluated by anion photoelectron spectroscopy and density functional theory calculations. The result provides the direct determination of the EA a values of the isolated CNBP, p-TP, p-QP, and TPB molecules, while EA a of BP, o-TP, and m-TP were estimated from the extrapolation of EA a vs cluster size. The excellent agreement between the experimental and calculated EA a were obtained.
