英文摘要	a novel n,n-bidentate dendritic bridging pyridine-imine ligand and its nickel complex were prepared and characterized by elemental analysis, fourier transform infrared spectrometry (ftir) and electrospray ionization-mass spectrometry(esi-ms). the dendritic nickel complex was used as a precatalyst in the oligomerization of ethylene with the co-catalyst ethyl dichloroaluminum(etalcl2), as well as a precursor in the oligomerization of 1-pentene. the effects of the reaction time, reaction pressure and the molar ratio of al/ni on the catalytic activities and the distribution of the product in the oligomerization were investigated. the dendritic nickel complex revealed the selectivity of higher olefins(c-10-c-14) reached up to 93% and the catalytic activity was 0.99x10(6) g/(mol ni.h) at the reaction time of 60 min, ethylene pressure of 0.5 mpa and the molar ratio of al/ni of 150 in the oligometization of ethylene. at the reaction time of 60 min and the molar ratio of al/ni of 300, the catalyst also had excellent catalytic performance in the oligomerization of 1-pentene. the selectivity of c-20 reached to 70.5% and the catalytic activity was 2.47x10(5) g/(mol ni.h). the dendritic nickel complex exhibited good catalytic activities and selectivities for higher carbon number olefins in ethylene oligomerization and 1-pentene oligomerization.
