Conjugated polymers have emerged as viable electronic materials for numerous applications. So far, the majority of work on conjugated polymers has been focused on linear one-dimensional polymers. Although a few of two-dimensional conjugated polymers, such as hyperbranched conjugated polymer have been reported to exhibit comparable charge transferring and processing properties to their linear counterparts, two-dimensional conjugated polymeric light-emitting materials have been less discussed in the literature. Here, we report the synthesis and light-emitting properties of fluorene containing hyperbranched conjugated poly(para-phenylene vinylene) derivatives through A2 and B3 type monomer. A synthesized fluorene containing hyperbranched polymer showed pure blue emission as film state at 462 nm in photoluminescence (PL) measurement and was found to showing almost no excimer emission peak even the polymer film was annealed at 80 oC. |
