Two-photon and Three-photon Absorption in an Organometallic Dendrimer

Samoc, Marek; Morrall, Joseph; Dalton, Gulliver; Cifuentes, Marie; Humphrey, Mark


Three at a time: The wavelength dependence of nonlinear absorption and non-linear refraction of a peripherally nitrophenylethynyl-functionalized first-generation arylethynylruthenium dendrimer (see picture; dppe = 1,2-bis(diphenylphosphanyl)ethane) was examined in the range 625-1500 nm by employing fs pulses. The compound is a strong two-photon absorber in the range 600-800 nm and an exceptional three-photon absorber in the range 1100-1200 nm. (Chemical Equation Presented).
