Abstract
A nano tridentate (O, N, O) donor Schiff base derived from salicylaldehyde and o-aminophenol (o-AP), 2-[[(2-hydroxyphenyl)imino]methyl]phenol (PIMP), and its nano Zinc(II) complex thin films, [Zn(PIMP)(H2O)]; ZnSB-1, are synthesized via Layer-by-Layer (LbL) self-assembly method at ambient temperatures. Elemental and metal analyses confirm a (1:1) ligand to metal stoichiometric ratio of ZnSB-1 nano complex. Scanning electron microscopy elucidates the nano nature of the self-assembled materials. Powder X-ray diffraction and SEM revealed an excellent crystallized nano ZnSB-1 complex. Fourier transform infrared spectra reveal the coordination nature between Zinc(II) and PIMP ligand in nano ZnSB-1 complex. Electron impact mass spectra and thermogravimetric analysis (TG) studies confirm the chemical structure of LbL self-assembled nano materials. TG/DTG studies also show an increase in the thermal stability of the ZnSB-1 nano complex over its nano PIMP precursor. The favorable conditions for ZnSB-1 nano thin film assembly are focused and studied through tuning a number of different parameters.
