Hyper-Rayleigh scattering and Stark spectroscopic studies show
that the complex salts [1–4]PF6 have larger static first
hyperpolarizabilities β0 than [5–8]PF6,
because the higher HOMO energy of a
RuII(NH3)5}2+ centre
more than offsets the superior π-orbital overlap in the purely organic
chromophores.
超雷利散射和斯塔克光谱研究表明,与 [5-8]PF6 相比,复盐 [1-4]PF6 具有更大的静态第一超极化率 β0,这是因为RuII(NH3)5}2+ 中心的 HOMO 能较高,足以抵消纯有机发色团中优越的 π 轨道重叠。
