摘要
Oligomers bearing dithienosilole as a pendent 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 (Phi = 0.72-0.76) in THF which are a little higher than that of monomeric dithienosilole DTS(TMS)(2). Applications of the oligomers to EL devices as hole transporting materials were examined and the maximum electroluminance of 2140 cd/m(2) was obtained from a device composed of ITO/oligomer/Alq(3)/Mg-Ag.
