Immobilization of the phenol((triethoxysilyl)propylimino) ligand (LH) on SBA15 and MCM41 afforded the ligands LH-SBA15 and LH-MCM41 respectively. The reactions of LH-SBA15 and LH-MCM41 with NiCl₂, CoCl₂ and FeCl₂ salts produced the respective materials [Ni(LH-SBA15)₂Cl₂], (Ni-SBA15), [Co(LHSBA15)₂Cl₂], (Co-SBA15), [Fe(LH-SBA15)₂Cl₂], (Fe-SBA15) and [Ni(LH-MCM41)₂Cl₂], (Ni-MCM41) in good yields. The functional group determination, morphology, physical and surfaced properties of the materials containing immobilized ligands and complexes were established from FT-IR, TGA, TEM, SEM-EDX, PXRD, ICP-AES, and nitrogen physisorption measurement techniques. Activation of the complexes on the surface with EtAlCl₂ as co-catalyst formed active catalysts for the oligomerization of ethylene affording mainly C₆ oligomers. The SBA-15 immobilized catalysts were more active than the corresponding MCM-41 materials, while Ni(II) catalysts performed better than the corresponding Co(II) and Fe(II) systems. The immobilized catalysts could be used in three cycles without significant loss of catalytic activity and selectivity.

将苯酚((三乙氧基甲硅烷基)丙基亚氨基)配体( LH )固定在SBA15和MCM41上分别提供配体LH-SBA15和LH-MCM41 。LH-SBA15和LH-MCM41与NiCl ₂、CoCl ₂和FeCl ₂盐的反应产生各自的材料[Ni( LH-SBA15 ) ₂ Cl ₂ ]、( Ni-SBA15 )、[Co( LHSBA15 ) ₂ Cl ₂ ], ( Co-SBA15 ), [Fe( LH-SBA15 ) ₂ Cl ₂ ], (Fe-SBA15 ) 和 [Ni( LH-MCM41 ) ₂ Cl ₂ ], ( Ni-MCM41 ) 产率良好。通过 FT-IR、TGA、TEM、SEM-EDX、PXRD、ICP-AES 和氮物理吸附测量技术，确定了含有固定配体和配合物的材料的官能团测定、形态、物理和表面性质。_{以EtAlCl 2}作为助催化剂活化表面络合物，形成主要提供C _{6的乙烯低聚活性催化剂}低聚物。SBA-15固定化催化剂比相应的MCM-41材料更具活性，而Ni(II)催化剂的性能优于相应的Co(II)和Fe(II)体系。固定化催化剂可以循环使用三个循环，而催化活性和选择性没有明显损失。
