摘要: We report blue emission from a series of alkyl and phenyl disubstituted polyacetylenes, i.e., poly(1-phenyl-1-alkynes) (PPhAs), with alkyne being n-propyne, n-butyne, n-octyne. Blue electroluminescence PPhAs is observed by employing cell an ITO (indium-tin oxide) coated glass substrate/PPhA/Mg/Al structure. The color luminescence changed blue-green to pure the intensity enhanced when length side chain increases, while neither nor monosubstituted polyacetylene shows intense luminescence. efficiency not efficiently improved doping common electron-transporting material 2-(4-biphenylyl)-5-(4- t-butylphenyl)-1,3,4-oxadiazole (PBD).
