We report in this letter the measurement of the hyperpolarizabilities of a series of donor-substituted triaryl-1,3,5-triazinanes-2,4,6-triones by hyper Rayleigh scattering (HRS). A remarkable transparencyânonlinearity trade-off is evidenced for these octupolar NLO-phores which might be accessed in a straightforward synthetic way and in a few steps from commercial isocyanates.
本信中,我们通过超瑞利散射(HRS)测量了一系列供体取代的芳香1,3,5-三嗪-2,4,6-三酮的超极化率。对于这些八极非线性光学分子而言,它们的透明度-非线性之间的优异平衡显而易见,这些分子可以通过简单的合成方法从商业异氰酸酯一步步轻松获得。
