摘　　要：One\|pot”reaction of 1,3,5 tribromobenzene with nonylmagnesium bromide,prepared by 1\|bromononane with magnesium in THF,catalyzed by Ni(PPh\-3)\-2Cl\-2,was used to obtain hyperbranched polyphenylene 1.The macromolecule was characterized by GPC with molecular weight M n=4247 and polydispersity PD =1 36.Under the conditin of Heck reaction catalyzed by palladium\|complexes,the terminal bromine groups on this macromolecule coupled with styrene and phenylacetylene,respectively,to provide correspondign hyperbranched polyphenylene 2 and 3 with stilbenyl and diphenylacetyl fluorophores on their surface.These two polymers both exhibited two bands E\-1 and E\-2 at near 260 nm and 300 nm in their UV spectra.In their powder photoluminescence spectra,the maximum emitting peaks at 401 nm and 386 nm in the range of blue luminescence were observed,respectively.One-pot' reaction of 1,3,5-tribromobenzene with nonylmagnesium bromide, prepared by 1-bromononane with magnesium in THF, catalyzed by Ni (PPh3)(2)Cl-2, was used to obtain hyperbranched polyphenylene 1. The macromolecule was characterized by GPC with molecular weight Mn = 4247 and polydispersity PD = 1.36. Under the conditin of Heck reaction catalyzed by palladium-complexes, the terminal bromine groups on this macromolecule coupled with styrene and phenylacetylene, respectively, to provide correspondign hyperbranched polyphenylene 2 and 3 with stilbenyl and diphenylacetyl fluorophores on their surface. These two polymers both exhibited two bands E-1 and E-2 at near 260 mn and 300 nm in their UV spectra. In their powder photoluminescence spectra, the maximum emitting peaks at 401 mn and 386 nm in the range of blue luminescence were observed, respectively.
