Abstract

The first photoionization onset, I_L¹, of pyrene was measured in seven liquid media comprising a dialectric hydrocarbon liquid and an electron attaching additive (A). The I_L¹ of pyrene was found to be independent of the dielectric hydrocarbon liquids and the concentration of A used. The average value (5.48 eV) of I_L¹ for all cyclic A's (c-C₇F₁₄, c-C₆F₁₂, c-C₈F₁₆) was lower by ≈0.40 eV compared to its value (5.88 eV) for the non-cyclic A (PFn-H). These findings have been rationalized on the basis of the time evolution of the photoionization and electron capture processes, and the electron attaching properties of A.
