Abstract
A luminescent polymer 3, consisting of a distyrylbenzene (PPV model ol igomer) moiety and an oligo(ethylene glycol) (PEO oligomer) moiety has been synthesized by two independent methods: a polymer-analogous Mits unobu reaction and conventional double displacement reaction. This new polymer is soluble in a variety of organic solvents, forms excellent, optically clear films, and exhibits strong fluorescence. A solution o f the polymer exhibits amplified stimulated emission with an emission bandwidth of 3 nm (fwhm) when pumped with a nitrogen laser. Initial ex periments to use this new polymer in light-emitting devices are descri bed.
