Three systematically varied triphenyl-amine-cored alkynylruthenium dendrimers were used for the study, which allowed the assessment of the impact of π-system lengthening through the metal center and effect of generation increase. The evaluation of nonlinear absorption and refraction properties was carried out using Z-scan experiments in the spectral range 532-1600 nm and by employing femtosecond pulses. Closed-aperture and open-aperture Z-scan measurement were conducted to determine spectral dependencies of absorptive and refractive components on the hyperpolarizability. The n-cored alkynylruthenium dendrimers showed 2PA behavior at wavelength below 1000 nm.Keywords: At-wavelength; Femtosecond pulse; Hyper-polarizability; Metal centers; Nonlinear absorptions; Organometallic complex; Refraction properties; Spectral dependency; Spectral range; Third order nonlinear optical properties; Triphenyl amines; Z-scan experiment200910.1002/adma.2008036692016-02-24
