Unformatted text preview: Pinang, Malaysia E-mail: nasertaha90@hotmail.com Schiff bases ligands have been studied for their wide applications in various fields such as catalysis, corrosion and sensors in addition to their biological activity towards cancer, tumor, antituberculous, antimalarial, and etc. We have been interested in preparing Schiff bases and their complexes in an effort to study and develop the understanding on the luminescence properties of these compounds. This work deals with the synthesis, characterization and photophysical properties of 6,6' -Di-tert-butyl-2,2'-[1,2phenylenebis(nitrilomethylidyne)]diphenol, for possible application as organic light emitting diodes and sensor. This ligand was synthesized and characterized by FTIR, elemental analysis, and single crystal X ray crystallography. Electronic spectra and fluorescence properties of this comp ound were investigated using UV-Vis and fluorescence spectroscopy in both solid state and in solution. Computational methods were employed to study its molecular properties such as absorption, molecular orbital and molecular orbital energy for this compound. The calculated results correlate well with the experimental findings and provide good understanding of the structural and electronic behaviors associated with this molecule. 156 3rd ICYC 2010 Universiti Sains Malaysia MAT-P6 23rd-25th June 2010 SYNTHESIS AND CHARACTERIZATION OF BIMETALLIC CATALYSTS FROM RICE HUSK ASH: AN INITIAL STUDY ON RUTHENIUM INCORPORATION INTO MCM-41 Jimmy Nelson Appaturi and Farook Adam School of Chemical Sciences, Universiti Sains Malaysia, 11800 Pulau Pinang, Malaysia E-mail: jagat39@gmail.com Rice husk ash (RHA) was used as a source of silica to synthesize MCM -41 via the sol-gel technique at 80 °C and pH 10. Initially a 10 % Ru was incorporated into the silica framework to give MCM -41-10Ru. The low angle XRD of RHA-MCM-41 indicated there were three reflections of SiO 2 crystals at 2θ equal to 2.4°, 4.0° and 4.8°, corresponding to hkl reflection planes 100, 110 and 200 respectively. The TEM images showed hexagonal or honey-comb structures w...
