Mechanochemical versus sol-gel silica loading of phenolate- and acetate-bridged dizinc Schiff base complexes: toward instant and inexpensive hybrids for controlled binding and release of Zn 2+ ion in pure water
The present invention relates to a hybrid manufacturing method using mechanochemical methods of common and inexpensive silica and Schiff base compounds, and provides a simple manufacturing process while maintaining activity as a metal ion sensor. The present invention relates to commercially available silica gels [rlysH 2 ] (compound 1), [Zn 2 (slysH) 2 Cl 2 ] (compound 2), [Zn 2 (rslysH) 2 (μ-OAc) 2 ] (Compound 3) and [Cu 2 (rslysH) 2 (NO 3 ) 2 (H 2 O) 3 ] (Compound 4), respectively, and then synthesized a silica hybrid material by a mechanical chemical method. [Slys or rlys = 6-amino-2-{(2-hydroxy-benzylidene) amino} hexanoate] The synthesized samples were analyzed by SEM-EDS. Absorption constant is between 5 and 20 minutes, 1.99 × 10 -4 (Compound (2) the number of molecules / unit SiO 2)(min) showed a 1. In the hybrid material is silica 1 according to the present invention shows a change in fluorescence "on-off" when Cu 2+ added in the addition of "off-on" and 2-silica of Zn +2. Use a mechanochemical method in all samples In addition to being stable in the bioenvironment, it is possible to use a 2-silica hybrid material with metal ions (Cu 2+ ) and Na 4 EDTA together as an “inhibitory” logic gate.
