本文报道了两种新的吡啶盐的合成,用元素分析、红外光谱、单晶X-射线衍射进行了表征。研究了它们的紫外光谱、荧光光谱和光限幅特性,发现它们的DMF溶液对1064nm皮秒脉冲激光表现出明显的光限幅特性。
In this paper, two new pyridinium salts were synthesized and characterized by elemental analysis, IR and single crystal X-ray diffraction. Their UV spectra, fluorescence spectra and optical limiting properties were studied. Their DMF solutions showed obvious optical limiting properties to 1064 nm picosecond pulsed laser.
