A pillared MOF, [Zn(OBA)(H2DPT)0.5].DMF (TMU-34), based on dihydro tetrazine functionalized pillar spacer (H2DPT=3,6-di(pyridin-4-yl)-1,4-dihydro-1,2,4,5-tetrazine) and V-shape dicarboxylate linker (H2OBA=4,4′-oxybis(benzoic acid)) was synthesized by reflux and ultrasonic methods. The effects of sonication time, initial concentration of reagents and sonication power on size and morphology have been optimized. This MOF has been characterized by scanning electron microscopy, FT-IR spectra, X-ray powder diffraction and N2 adsorption at 77K. Bulk and nano samples of TMU-34 have been applied in cation sensing for detection of Al(III) in presence of other cations (Na(I), Mg(II), Sr(II), Al(III), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Pb(II), Hg(II),Cr(III), Li(I), Fe(III), K(I)). The results show that nano powder of TMU-34 with uniform separated plate-like morphology (TMU-34-F) has higher detection limit and short response time compared to bulk material. So, in this work we show the application of luminescent metal-organic frameworks synthesized by sonochemistry approach in effective cation detection.
