Herein, a new cationic Cu(II)-based porous and water stable metal organic framework (MOF), [{Cu(bipy)1.5(H2pdm)}βoxO3βox]n (Cu-MOF-1) is designed using pyridine-2,6-dimethanol (H2pdm) and 4,4′-bipyridine (bipy) through slow evaporation process. The MOF is characterized by FTIR, PXRD, TGA, magnetic and single crystal XRD anal. The structural unit of Cu-MOF-1 consists of two Cu(II) ions bridged by bipy and supported by the H2pdm. This material exhibits excellent sensing ability for nitrobenzene (NB) and fluoride ion (F-) in 100% aqueous medium with ultra-low limit of detection (LOD) i.e., 0.093 and 1.203 ppb for NB and F-, resp. The detection of NACs is governed by PET and FRET mechanism while vapor pressure plays major role for NB detection showing highest fluorescent quenching of 96.4%. Moreover, the MOF revealed high water stability, significant recyclability and microporosity. The MOF was also employed for adsorption and separation of methylene blue from the mixture of three dyes (methylene blue, rhodamine-B and methyl orange). At equilibrium, the removal percentage of Cu-MOF-1 for MB is 98.23% and the mechanism of dye adsorption is also explored. Thus, the present MOF comes out as a sustainable multifunctional material for aqueous phase sensing of hazardous nitrobenzene and fluoride ions, as well as an excellent dye adsorbent. In addition to this study using 2,6-Pyridinedimethanol, there are many other studies that have used 2,6-Pyridinedimethanol(cas: 1195-59-1Category: alcohols-buliding-blocks) was used in this study.
2,6-Pyridinedimethanol(cas: 1195-59-1) belongs to pyridine. When pyridine is adsorbed on oxide surfaces or in porous materials, the following species are commonly observed: (i) pyridine coordinated to Lewis acid sites, (ii) pyridine H-bonded to weakly acidic hydroxyls, and (iii) protonated pyridine. At high coverage, physisorbed pyridine and protonated dimers can also be observed.Category: alcohols-buliding-blocks
