Nonlinear optical properties of thienyl and bithienyl iodonium salts as measured by the Z-scan technique

Year: 2002

Type: article

Abstract: The linear and nonlinear optical properties for a series of thienyl- and bithienyl(aryl)iodonium triflate salts 1–4 have been determined. The energy of the linear absorption maxima for salts 2–4 experiences only a minor shift to lower energy as the aryl group is made more electron deficient. In contrast, the real parts of the second hyperpolarizabilities, γ R , experience a 10-fold increase. Open-aperture Z-scan data for all three bithienyl iodonium salts 2–4 demonstrate the presence of three-photon absorption under irradiation at 650 nm.
