A Multiresponsive Metal–Organic Framework: Direct Chemiluminescence, Photoluminescence, and Dual Tunable Sensing Applications

Abstract

By incorporating an anthracene moiety into a framework, a multiresponsive luminescent metal–organic framework (1) has been synthesized, which exhibits both direct chemiluminescence (CL) and dual tunable photoluminescence. By utilizing the CL, 1 has been explored as a selective visual sensor for hydrogen peroxide. Moreover, 1 also exhibits tunable fluorescence response toward different analytes. For electron‐rich aromatics, “turn‐on” and “turn‐off” responses can be simply switched by varying the excitation wavelength. For nitroaromatics, 1 exhibits novel linear quantitative quenching response. Density functional theory (DFT) calculations and experiments have been carried out to study the unique fluorescence response. The multiple luminescence properties and dual tunable sensing response indicate that incorporating anthracene moieties into frameworks should be a promising strategy to develop unprecedented luminescent materials with remarkable sensing properties.

“…These are mainly derived from the emissions of chemical industries, automobile exhausts, building blocks, etc 23,24 . Therefore, an effective probe of VOCs is another important task for both environment protection and human health.…”

A Chemiluminescent Metal–Organic Framework

“…The peroxyoxalate chemiluminescencer eaction, [1g, 4] ar eaction that is of interest for the chemicalg eneration of light as well as the detection of hydrogen peroxide and oxalic acid, was applied to Cd 2 L 2 (DMF) 2 with Lb eing 3,3'-(anthracene-9,10-diyl)diacrylate, which acted as the luminophore. [5] Because the BET surface area of this material was very low,t he chemiluminescence came most probably only from luminophoresa tt he crystal surfaces, rather than from luminophores inside the crystals. Here we report on the peroxyoxalate chemiluminescence reaction with PAP-UiO, aZ rbased MOF containing 4,4'-(anthracene-9,10-diyl)dibenzoate as the linker.9 ,10-Diphenylanthracene is known to be ah ighly efficient luminophore in the peroxyoxalate chemiluminescence reaction.…”

“…The luminol reaction was used in combination with MOFs, whereby the luminophore was a guest and not part of the MOF scaffold, and was consumed during the chemi‐luminescence reaction. The peroxyoxalate chemiluminescence reaction, a reaction that is of interest for the chemical generation of light as well as the detection of hydrogen peroxide and oxalic acid, was applied to Cd 2 L 2 (DMF) 2 with L being 3,3′‐(anthracene‐9,10‐diyl)diacrylate, which acted as the luminophore . Because the BET surface area of this material was very low, the chemiluminescence came most probably only from luminophores at the crystal surfaces, rather than from luminophores inside the crystals.…”
