摘要：

Two series (A and B) of organically modified silicate gels complexed with Cu'' have been synthesized by a two-step reaction procedure: (1) coordination, (2) sol-gel process. Series A consists of unidentate ligands [L] = H2N(CH2)3SiO3/2 and series B of bidentate ligands [L'] = H2N(CH2)2NH(CH2)3SiO3/2. The gels complexed in bulk with Cu(II) have been analysed by electron paramagnetic resonance EPR spectroscopy at specific stages of thermal decomposition. The EPR data are complemented with thermoanalytical methods: differential thermal analysis (DTA), differential thermogravimetry (DTG) and thermogravimetry (TG).
