- Abstract
In this study, the electroluminescent (EL) properties of electrochemically cross-linkable, terthiophene terminated poly(benzyl ether) dendrimers (G0-3T and G1-3T DNs) are investigated. In noncross-linked 3T DNs, there is either no emission or a low-intensity emission due to poor charge transfer of the isolated terthiophene (3T) oligomers at the periphery of the DNs. However, increase in the length of conjugation via electrochemical cross-linking leads to the emission of a yellowish color. It is seen that the emission of this color is dependent on the dendritic structures and effectively controlled charge trapping. Thus, these results suggest that the dendritic molecular structure, which is associated with the conjugated length of the emissive peripheral units and the generation of the dendrimers, is an important factor in controlling EL properties.
