چکیده
|
Solid-state conversion of nai coordination polymer nanostructure, synthesized by sonochemical procedure, to tli coordination polymer has been observed upon liquid-assisted mechanochemical reaction of [na2tp] n (1) (h2tp = terephthalic acid), with tlno3. during this conversion, ion exchange process of na(i) with tl(i) was occurred and [tl2tp] n (2) was synthesized. the x-ray diffraction (xrd) pattern of 2 after mechanochemical reaction of it with nano3 indicated that this transformation is irreversible. compounds 1 and 2 were characterized by ir spectroscopy, x-ray powder diffraction (xrd), elemental analysis, thermogravimetric and differential thermal analyses and scanning electron microscopy.
