Preparation and behavior of calix[4]arene-containing organosilicone resins(I)

Two organosilicone resins (PCSN and PCSNN) were prepared from 1,3-bis-glyci dyl-p-tert-butyl-calix[4]arene(BGC) via condensation with triethoxyaminopro pylsilane or triethoxy-4-azo-6-aminohexylsilane, followed by copolymerizati on with tetraethoxysilane, respectively. The resins exhibit high thermostab ility and adsorb nitrogen under elevation temperature. The adsorption capac ity of PCSN and PCSNN toward Mg(II), Cu(II), Pb(II), Hg(II), and Au(III) ca tions was determined and the thermodynamic parameter of the resins toward A u(III) ion was deduced. Human serum protein was also adsorbed on the resins . (C) 2001 John Wiley & Sons, Inc.
