摘要:

通过层层静电自组装技术制备了基于电致变色多酸P8W48与发光邻菲罗啉钌Ru(phen)的杂化红光薄膜[(PEI/P8W48)m/PEI/PSS/Ru(phen)/PSS]15[m=1, 3, 5; PEI=聚乙烯亚胺; PSS=聚(4-苯乙烯磺酸钠)]. 利用紫外-可见光谱对薄膜的组成及增长进行了表征; 通过循环伏安法对薄膜的电化学氧化还原性质进行了考察; 通过荧光光谱对薄膜的发光性质进行了研究. 结果表明, 薄膜在外加氧化还原电位下呈现出可逆的电致变色-荧光开关性质; 在阶跃电位-0.85 V/0.85 V下循环50次, 其电致变色及荧光开关性能没有明显的减弱, 体现了良好的电化学稳定性.

Abstract:

The red luminescence films [(PEI/P8W48)m/PEI/PSS/Ru(phen)/PSS]n[m=1, 3, 5; PEI=Poly(ethyleneimine); PSS=poly(sodium 4-styrenesulfonate)] were fabricated by layer-by-layer assembling method based on electrochromic polyoxometalate P8W48 and luminescent complex Ru(phen). The composition and thicking of the films were characterized by UV-Vis spectrophotometry. The electrochemical and luminescent properties were studied by cyclic voltammetry and fluorescence spectrophotometry, respectively. The composite films displayed reversible electrochromic and electroswitchable luminescence properties during redox potential switching. The electrochromic and luminescence switching abilities of the films were almost not changed by double potential steps(-0.85 V/0.85 V) for 50 cycles, suggesting good electrochemical stability of the films.

Key words: Polyoxometalate, Controllable self-assembly, Luminescent film, Electrochromic property, Luminescence switch
