Abstract:	摘要： A series of novel multipolar fluorophores based on tetra-substituted olefinic scaffold using functionalized fluorenyl and indenofluorenyl units as the aryl substituents has been synthesized and investigated for their two-photon-related properties in the femtosecond and nanosecond time domains. When probed by the femtosecond pulses, these chromophores are found to possess appreciable intrinsic two-photon absorptivities with their local maxima very close to the short-wavelength end of the dynamic tuning range of a Ti: sapphire laser. While under the irradiation of nanosecond pulses, these dye molecules exhibit promising nonlinear optical-power-attenuation properties across the visible-to-near infrared region. Combining with their medium-high fluorescence quantum efficiencies, such archetype represents a new class of structures that could be utilized as effective broadband optical power-limiters and frequency up-converters especially with great potentiality to work in the visible regime. [Display omitted] •A series of tetraarylethylene-type chromophores are synthesized and characterized.•The studied chromophores exhibit wide spectral range of linear transparency.•These compounds show strong nonlinear attenuation in the visible-to-near IR region.•Two-photon-based optical-power-limiting in the visible range is demonstrated. 出版者： Elsevier Ltd 出版日期： 2016-11 出處： Dyes and pigments, 2016-11, Vol.134, p.325-333 版權： 2016 Elsevier Ltd 識別號： ISSN: 0143-7208 識別號： EISSN: 1873-3743 識別號： DOI: 10.1016/j.dyepig.2016.07.027
