用单晶x射线衍射分析表征了反式4-（4′-（N，N-二烷基氨基苯乙烯基））-N-甲基吡啶[Mo6O192−][烷基= Et(POM1), Pr(POM2), N- bu （POM3）和Me，羟乙基（POM4）] 4种新型有机-无机杂化染料的结构。有机发色团与多金属氧酸盐的杂交增强了它们的双光子吸收截面和热稳定性。利用吸收光谱和荧光光谱研究了该杂化染料在溶液和固体状态下的线性光学性质。利用z -扫描技术获得了双光子吸收截面δ和系数β。研究了染料结构与光学性能之间的关系。
The structures of four novel organic–inorganic hybrid dyes, namely trans-4-(4′-(N,N-Dialkylaminostyryl))-N-Methyl-pyridinium[Mo6O192−] [alkyl = Et(POM1), Pr(POM2), n-Bu(POM3) and Me, hydroxyethyl(POM4)], were characterized by single crystal X-ray diffraction analysis. Hybridization of the organic chromophores with polyoxometalate enhanced their two-photon absorption cross sections and thermal stability. The linear optical properties of the hybrid dyes were investigated using absorption and fluorescence spectra in both the solution and solid states. The two-photon absorption cross section δ and coefficient β were obtained using the Z-scan technique. Correlations between dye structure and optical property were investigated.
