Popis:	Novel poly(p-phenylene vinylene)s (PPVs) 6 and 7 wrapped with rigid 1,3,5-phenylene dendrons have been synthesized by using stepwise Suzuki coupling reactions and the following polymerization. The synthesized dendritic PPVs possess high thermal stability and good film-forming properties. The fluorescence spectra of the polymer films demonstrate the effectiveness of side chains in preventing π-stacking among conjugated backbones without causing undesirable shifts in fluorescence spectra. Electroluminescent devices have been constructed in the configuration ITO/PEDOT:PSS/6 or 7/Ca/Al, and their light-emitting and electrical characteristics have been investigated. The efficiency of organic light-emitting diodes (OLEDs) devices is strongly affected by the size of the phenylene dendron. The color of OLED devices could be tuned by the doping of fluorescence into the dendritic PPV layer.
