Photoactive ternary rare earth complex hybrids with sulfoxide functionalized silica and PMMA (or Phen).
A series of ternary rare earth complexes were covalent grafted to the inorganic Si-O networks through the novel bifunctional silylated monomer BBMSSi (BBMS = Bis [benzoylmethyl] sulfoxide). FT-IR, NMR, XRD, TGA, SEM, DRS and photoluminescence properties were used to characterize the obtained hybrid materials. Scanning electron micrograph results revealed hybrids exhibiting homogeneous morphology with large particle size of 100-200 microm and no phase separation. Photoluminescence measurements indicated hybrids with characteristic red and green luminescence. In addition, the existence of the polymeric chain PMMA and 1,10-phenanthroline in different hybrid systems present different microstructure and luminescence behavior.
