A Luminescent Metal–Organic Framework as a Turn‐On Sensor for DMF Vapor

Abstract

A real turn-on: a luminescent lanthanide metal-organic framework shows strong and fast turn-on responses to N,N-dimethylformamide (DMF) vapor. The selective turn-on effect is triggered mainly by DMF-ligand interactions, along with the removal of quencher, water, from the metal coordination sphere.

Synthesis, Crystal Structure of a Novel Mn Complex with Nicotinoyl-Glycine

“…Coordination compounds, a class of newly developed porous inorganic-organic hybrid materials, have attracted much attention, due to their diverse and easily tailored structures [1][2][3][4][5], and their tremendous potential applications in nonlinear optics, catalysis, gas absorption, luminescence, magnetism and so on [6][7][8]. To obtain desired coordination compounds, hydrogen bonds, π-π interactions and Van der Waals interactions must be carefully considered [9]; also, the appropriate use of the well-designed multidentate nitrogen ligands and organic carboxylic acid ligands plays an important role in the synthesis of coordination compounds [10].…”

MIL-68 (In) nano-rods for the removal of Congo red dye from aqueous solution

“…Metal-organic frameworks (MOFs), as a new class of inorganicorganic hybrid materials based on metal ions coordinated by multidentate organic bridging ligands, have received a great deal of attention because of their attractive potential applications in gas adsorption/separation, catalysis, sensing, drug delivery, and magnetism [5][6][7][8][9][10]. In the past few years, MOFs have been explored for the adsorption and removal of dyes from aqueous solution, due to their diverse compositions and structure types, large surface area, tunable pore size, and coordinatively unsaturated or saturated metal sites to regulate the adsorption ability [11][12][13][14][15][16][17][18][19].…”

Group 3 Elements and Lanthanide Metals

“…A "turn-on" detection of DMF in the vapor phase was observed for [Eu 2 (L * ) 3 (H 2 O) 4 ]3DMF (L * = 2 ′ ,5 ′ -bis(methoxymethyl)-[1,1 ′ :4 ′ ,1 ′′ -terphenyl]-4,4 ′′ -dicarboxylate) [199]. Only DMF showed a respective strong effect out of a broad variety of solvents including acetone, CH 2 Cl 2 , benzene, Et 2 O, EtOAc, DMF, EtOH, hexane, MeCN, MeOH, and THF.…”
