Strategies to fabricate metal–organic framework (MOF)-based luminescent sensing platforms

Abstract

This review introduces the recent advance in the construction of MOF-based sensing platforms in chemical sensing and biosensing. In particular, the fabricating strategies of MOF-based luminescent sensors and the sensing mechanisms are reviewed.

Two new CdII MOFs of 1,4-bis(1H-benzimidazol-1-yl)butane and flexible dicarboxylate ligands: luminescence sensing towards Fe3+

“…1, the Cd1 centre is six-coordinated by four O atoms (O1, O2, O3 and O4) from two distinct Pim 2À ligands and two N atoms (N1 and N3) from two distinct bbimb ligands, resulting in a distorted CdN 2 O 4 octahedral geometry. The Cd-N [2.250 (4) and 2.263 (4) Å ] bonds are shorter than the Cd-O bonds [2.315 (3)-2.460 (3) Å ] and the angles around the Cd II centre range from 55.51 (11) to 153.52 (12) , which are in the normal range for reported Cd II MOFs (Bouchene & Bouacida, 2019;Shao et al, 2019;Wang et al, 2018). In the crystal structure of 1, the Pim 2À ligand adopts a 2 -2 : 2 coordination mode connecting two Cd1 centres.…”

“…Metal-organic frameworks (MOFs) used as luminescence sensing materials have attracted considerable interest due to a number of advantages, such as short response time, measurement flexibility and high sensitivity (Dong et al, 2019;Wang et al, 2019a). Luminescent MOFs have been widely explored in the detection of toxic pollutants, such as inorganic heavy metal ions, toxic anions and small organic molecules (Liu et al, 2019;Rasheed & Nabeel, 2019), which play important roles in the protection of the environment and human health. Therefore, the rational design and construction of luminescent MOFs has attracted significant interest.…”

Three Novel Zn-Based Coordination Polymers: Synthesis, Structure, and Effective Detection of Al3+ and S2− Ions

“…Molecules 2020, 25, x FOR PEER REVIEW 2 of 14 [14][15][16][17]. In recent years, coordination polymers (CPs) used as fluorescent sensors have been successfully applied in the determination of various analytes such as metal ions (Fe 3+ , Cr2O4 2− , etc.)…”

“…Coordination polymers (CPs) have aroused much interest, owing to their potential applications in catalysis [5][6][7], adsorption [8,9], separation [10], electrochemistry [11][12][13], and as chemical sensors [14][15][16][17]. In recent years, coordination polymers (CPs) used as fluorescent sensors have been successfully applied in the determination of various analytes such as metal ions (Fe 3+ , Cr 2 O 4 2− , etc.)…”

Three new coordination polymers based on bis(4-(4H-1,2,4-triazol-4-yl)phenyl)methane: syntheses, structures, multiresponsive luminescent sensitive detection for antibiotics and pesticides, and antitumor activities

“…Coordination polymers (CPs) from the assembly of inorganic clusters and tunable organic linkers are extensively investigated as promising materials for applications in various elds, [1][2][3][4] such as life sciences, 5,6 environmental areas, [7][8][9][10] medicinal science 11,12 and the nuclear industry. 13 Due to the simultaneous introduction of organic ligands and metal centers, some specic properties have been endowed to the CPs with versatile functions like biological activity, [14][15][16] molecular magnetism, 17,18 electronic conductivity, 19 second-order nonlinear optics (NLO) activity, 20,21 ferromagnetism, 22,23 catalysis, [24][25][26] and molecular recognition.…”
