Polymer light-emitting diodes (PLEDs) have attracted much attention from academia and industry field because PLED has advantage property that is well-suited to flexible lighting and solution processed device. In this paper, we suggest new blue emitting polymer based on pyrene, poly(9-(3-Vinyl-phenyl)-pyrene) (PVPPy). From NMR data, vinyl group protons were disappeared and aromatic protons showed broad proton peaks because of polymer characteristics. PVPPy film can be obtained from spin coating with solution used by common solvents. It exhibited photoluminescence(PL) maximum value of 468 nm and full width at half maximum (FWHM) value of 73 nm. Three dopants for green, red, yellow were used to PVPPy, all energy transfer was happened well. |
