a novel facile synthesis route for nano-sized zn(ii) schiff base complex and nano-sized znse/zno

Nano- sized of 2,2'-((1e, 1e')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) zn (ii) schiff base complex was quickly synthesized in mild condition by ultrasonic irradiation. the zn (ii) complex was characterized by ft-ir, 1hnmr, fesem as well as electronic and fluorescence property measurements. based on the results of these analyses, the geometry of zinc (ii) schiff base complex suggested a square-planar geometry. antimicrobial activities of the ligand and zinc (ii) complexes were also investigated. the electronic and fluorescence bands of nano complex show a shift in comparison to the bulk sample analogue, duo to the reduction of particle size in nano scale. in continuation of our study, znse/zno nano sized with 30 nm in average sizes was prepared, by reflux condensation method, using this complex as a new precursor.
