“…Usually, the chemical sensors could have a “turn on” or “turn off” response to small molecules [ 13 , 14 , 15 ]. The characteristic of a good sensor is usually summarized as “4S”: sensitivity, selective, stability and speed of response [ 16 , 17 , 18 , 19 , 20 , 21 , 22 ].…”

Metal-organic frameworks (MOFs) have been rapidly developed for their broad applications in many different chemistry and materials fields. In this work, a multi-dentate building block 5-(4-(tetrazol-5-yl)phenyl)-isophthalic acid (H3L) containing tetrazole and carbolxylate moieties was employed for the synthesis of a two-dimensional (2D) lanthanide MOF [La(HL)(DMF)2(NO3)] (DMF = N,N-dimethylformamide) (1) under solvothermal condition. The fluorescent sensing application of 1 was investigated. 1 exhibits high sensitivity recognition for antibiotic nitrofurantoin (Ksv: 3.0 × 103 M−1 and detection limit: 17.0 μM) and amino acid l-tyrosine (Ksv: 1.4 × 104 M−1 and detection limit: 3.6 μM). This work provides a feasible detection platform of 2D MOFs for highly sensitive discrimination of antibiotics and amino acids.

“…MOFs is a type of porous crystalline material with two-dimensional or three-dimensional structure composed of inorganic nodes (metal ions/clusters) and organic ligands through selfassembly. 77,78 The pore size of MOFs can be adjusted by changing the synthesis conditions, material types, and proportion. 79 MOFs have good gas storage capacity, and the absorption and desorption of gas can be controlled by some methods.…”

Application of ethylene‐regulating packaging in post‐harvest fruits and vegetables storage: A review

Ethylene is a key hormone to promote the ripening of fruits and vegetables (F&V). It is detrimental to the transportation, storage, and sale of F&V. In order to control the maturation of F&V and reduce their losses, many ethylene-regulating packaging (ERP) have been developed. In this review, we first introduced the synthesis pathway of ethylene. Next, we divided ERP into four categories: ethylene-degrading packaging, ethylene-adsorbing packaging, modified atmosphere packaging, and bioactive packaging according to the way of regulating ethylene, clarifying the regulation mechanism and characteristics of various types of packaging. Finally, we predicted the future development direction of ERP.

“…Furthermore, to construct chiral MOFs for enantioselective sensing, a straightforward approach is to use homochiral ligands, [22, 23] but this method suffers from the high cost of the starting materials and complicated synthetic procedures. As an alternative approach, chiralization of achiral MOFs is a more facile and low‐cost approach that can be achieved by post‐synthetic modification [24, 25] . For example, MIL‐101 was chiralized by L‐proline‐derived auxiliary ligand for chiral catalysis [26] .…”

Bifunctionalized Metal–Organic Frameworks for Pore‐Size‐Dependent Enantioselective Sensing

Porosity is a fundamental property of metalorganic frameworks (MOFs). However, the role of the pore size has always been underestimated in MOF-based luminescent sensors for enantioselective sensing. The construction of isoreticular MOFs (IRMOFs) with variable pore sizes and the synergy between chirality and luminescence is challenging. Herein, a general strategy was developed to introduce chirality into two well-known IRMOF-74 analogs with nanochannels of identical shapes but different pore sizes by functionalizing the open metal site under mild conditions. To enhance the detection accuracy, a second luminescent center was introduced into the IRMOF-74 system to achieve ratiometric sensing. The two bifunctionalized IRMOF-74 compounds exhibited pore-size-dependent sensing performance for enantiomers. This study not only provides a convenient method to construct chiral MOFs as advanced sensing materials but also reveals the fundamental of the pores in MOF-based luminescent sensors.
