Synthesis and characterization of poly(p.phenylene vinylene) polymers containing the quinoxaline group
Novel poly (p-phenylenevinylene) polymers containing the quinoxaline group were prepared by the Horner-Wadsworth-Emmons reaction of the various diphosphonic acid diethyl ester with a dialdehyde monomer. The spectral properties of products so obtained were characterized by UV-visible and fluorescence spectroscopy. The UV-visible absorbance of these polymers showed absorption bands at ca. 432-440 nm, which corresponding to the pi-pi* transition of the conjugated system. Their maximum fluorescence appeared at ca. 488 similar to 498 nm. The resulting polymers showed greenish blue emission in solution and an orange emission in solid state.
