“…In terms of the quenching process, luminescent quenching can be divided into two parts: dynamic quenching and static quenching. While for some luminescence quenching only one type of process either dynamic or static is involved, most quenching processes include both, such as the coexistence of dynamic and static quenching when an Eu(III)-doped Zn-MOF, Zn 3 (BTC) 2 : 4%Eu(III), was exposed to nitrobenzene (NB) [ 51 ].…”

HIGHLIGHTS • An overview on photophysical properties of conductive metal-organic frameworks (MOFs) including photoconductivity and photoluminescence is provided. • Miscellaneous applications of MOFs with photophysical properties are discussed. • Recent advances in integration of photoactive MOFs with practical devices are summarized. ABSTRACT Metal-organic frameworks (MOFs) are a class of hybrid materials with many promising applications. In recent years, lots of investigations have been oriented toward applications of MOFs in electronic and photoelectronic devices. While many high-quality reviews have focused on synthesis and mechanisms of electrically conductive MOFs, few of them focus on their photophysical properties. Herein, we provide an in-depth review on photoconductive and photoluminescent properties of conductive MOFs together with their corresponding applications in solar cells, luminescent sensing, light emitting, and so forth. For integration of MOFs with practical devices, recent advances in fabrication of photoactive MOF thin films are also summarized.

“…After integrating Eu 3+ , however, the peak at 533.80 eV diminished and simultaneously, the peak at 531.95 shifted to 532.18 eV. Undoubtedly, the above binding energy changes of O 1s should be ascribed to the influence of Eu 3+ , implying the presence of a weak interaction between Eu 3+ and O sites . Fourier transform infrared spectrometry (FTIR) analyses confirmed the formation of the above weak interaction.…”

Facile and rapid detection of residual organic pesticides on the fruits and vegetables has recently drawn increased attention in the food safety field. Herein, a surfactant-assisted solvothermal route with subsequent post-modification was designed for the preparation of Eu3+-functionated Zn-BDC ultrathin nanosheets (labeled as Eu3+@Zn-MOF-NS, BDC: 1,4-benzenedicarboxylate) with the thickness of 5 nm. The as-obtained Eu3+@Zn-MOF-NS could be homogeneously dispersed in aqueous systems to form a highly-stable collosol. Under the UV excitation of 325 nm, the as-obtained Eu3+@Zn-MOF-NS displayed red photoluminescence emission of Eu3+ ions, which could be notably quenched by an organochlorine pesticide, 2,6-dichloro-4-nitroaniline (DCNA), without interferences from ions, organic small molecules, and other pesticides. The detection limit and K sv were 0.17 μM (35 ppb) and 3.2 × 105 M–1 in the water system, respectively. Moreover, the present 2D Eu3+@Zn-MOF sensor was also employed for the detection of DCNA in Chaohu Lake water and tap water and in apple, cabbage, and pakchoi samples with the relative standard deviation (RSD) ranging from 4.74 to 9.77%. Further investigations revealed that the competitive absorption between DCNA and the as-obtained Eu3+@Zn-MOF-NS resulted in the fluorescence quenching of the probe.

“…5.16 eV. 27 Since nitrobenzene is an electron-deficient molecule it acts as an electron acceptor and MOF as an electron donor. The excited-state of the MOF and the ground state of the nitrobenzene are here quenched by a photoinduced electron transfer shown in Fig.…”
