合成了三种烷氧基取代的金属酞菁铅,利用元素分析、红外光谱、核磁共振氢谱(HNMR)等方法,验证了化合物的分子结构。将它们分别掺入聚甲基丙烯酸甲酯(PMMA)中,制备出具有非线性光学性质的复合材料。测试了它们在甲基丙烯酸甲酯中的可见光谱(200~800nm)。用波长为532nm的YAG倍频调Q脉冲激光以8ns的脉冲速率测试复合材料的反饱和吸收的光限幅特性,使用现象学的方法对它们的光限幅现象进行了拟合。拟合结果与实验结果基本一致。三种化合物中叔丁烷氧基酞菁铅反饱和吸收效果最好,这是由于短支链基团有利于酞菁环自身结构的共轭性提高,并能够阻止酞菁分子间发生低聚。 Three alkoxy-substituted metal phthalocyanines were synthesized. The molecular structures of the compounds were verified by elemental analysis, IR, HNMR and so on. They are respectively incorporated into polymethylmethacrylate (PMMA) to prepare a composite with nonlinear optical properties. Their visible spectra in methyl methacrylate (200-800 nm) were tested. The optical limiting properties of the reverse saturable absorption of the composites were tested at a pulse rate of 8 ns with a YAG frequency doubling Q-switched laser at a wavelength of 532 nm. Their optical limiting phenomena were fitted using the phenomenological method. Fitting results and experimental results are basically the same. Among the three compounds, tert-butoxycarbonyl phthalocyanine has the best reverse-saturating absorption effect because the short-chain branch group is conducive to the increase of the conjugation of the phthalocyanine ring itself and prevents the oligomerization of phthalocyanine molecules .
