| Abstract: | The Preparation of cyclo -multidentate squeric aeid hgand SQAL was reported the struxcture of which was characterized by eiemental analysis. IR. UV/Vis. MS. HNMR. The spectroscopic characterization of this compound was aiso discussed. It has strong absorption band over 700-800nm. Addition of TiO2 colloids to a solution of SQAL resulted in the increase of optical density . fluorescence quenching for it. The experimental data provides evidence of powerful interaction between SQAL and Tio2 nanoparticles. The apparent association constant of 3905mol.L with nanoparticle TiO2 was determined from the data of the fluorescence quenching by TiO2 colloids. |
