摘要:
We present a new electroactive polymer, the polystyrene-oligo(phenylene-vinylene) (PS-OPV), in which nanostructured photoactive conjugated phenylene-vinylene segments are attached as sidechains to the polystyrene backbone. The number of phenylene-rings of the OPV segments is very homogeneous (2-4 rings), as the UV/vis absorption and photoluminescence (lambda(max)=430nm) spectra compared to OPV oligomer spectra show. The photoluminescence quantum yield is very high. Electrochemical measurements were used to determine the electronic structure of the conjugated polymer. The PS-OPV was successfully used as a blue light emitting layer in single and multilayer electroluminescence devices.
