were prepared by radical polymerization of the corresponding dithienosilole monomer using AIBN as an initiator. The resulting oligomers exhibited high solubility in common organic solvents and strong photofluorescences (Φ = 0.72–0.76) in THF which are a little higher than that of monomeric dithienosilole DTS(TMS)2. Applications of the oligomers to ELdevices as holetransporting materials were examined
通过使用AIBN作为引发剂使相应的二噻吩并硅醇单体进行自由基聚合来制备带有二噻吩并硅醇作为侧基的低聚物。所得的低聚物在普通有机溶剂中显示出高溶解度,并 在THF中具有较强的光致荧光(Φ = 0.72–0.76),略高于单体二硫代硅醇DTS(TMS)2。检查了低聚物作为空穴传输材料在EL器件上的应用,并从由ITO /低聚物/ Alq 3 / Mg-Ag组成的器件中获得了2140 cd / m 2的最大电致发光度。
