摘　　要：合成了3个最大吸收波长在近红外区域的硫代双烯镍络合物,用元素分析、核磁共振氢谱、质谱及红外光谱表征了中间体及产物的结构,并测试了染料在溶液和PMMA滤光片中的光谱性质。结果表明,染料的最大吸收波长与溶剂的极性成正比,其中结构为(RCSCSR)2Ni(R=C6H4-C(CH3)3)的染料,自身的光稳定性最好;当掺杂在PMMA滤光片中时,它们的最大吸收波长位置与在溶剂中的相近,光稳定性能比在溶液中好。Three Dithiolene Metal Complex NIR Dyes were synthesized and characterized by means of elemental analysis, ^1H NMR, mass spectrum and infrared spectra. The spectral properties and photostabilization of the dyes were tested in solvents and PMMA filter. The results showed that the dye containing tertbutylbenzene groups had better photostabilization. The maximum absorption wavelength of dyes were in proportion to the polarity of the solvents. When dyes doped in PMMA filter, the maximum absorption wavelength were near to their relative ones in solvents and the photostabilization were better than them.
