摘要：

Solid porous ligands containing bound diaminoethane groups have been prepared by hydrolytic condensation of Si(OEt)4 with (MeO)3Si(CH2)3NH(CH2)2NH2. In aqueous solution, essentially all the ligand groups react with H3O+ ions, and a large proportion reacts with divalent metal ions (Co2+, Ni2+, Cu2+). EPR and visible spectra suggest that 1:1 and 2:1 complexes are formed. Preliminary data suggest that such materials have potential for ion-exchange.
