6'-dibromo-2
2'-bisbutoxy-1
1.-binaphthyl((R)-M-2)with 1
4-divinyl-2
3-bisbutoxy—naphthalene(M-3)via Heck coupling reaction catalyzed by PdAc2
respectively.Their structure and properties were characterized by NMR

fluorescent spectroscopy and thermal analysis.The butoxy substitutents on naphthyl and binaphthyl rings as side chains of the polymers can improve their solubility in organic solvents and make them easy to be processed as electro—optical sensors.Both polymers show high thermal stability and have strong blue fluorescence due to the efficient energy migration from the extended π-electronic structure of the polymers to the chiral binaphthyl core.Photoluminesenee effcieneies(φPL)of P-1 and P-2 are 0.42 and 0.48
and they are expected to be used as blue—green emitting polymet matefials.
