“…Zr-based MOF-525 and MOF-545 were also fabricated using a sonochemical procedure, utilizing ZrCl4 8H2O as the metal precursor and tetrakis (4-carboxyphenyl) porphyrin as the organic linker [84]. Subsequent SEM analysis indicated that MOF-525 exhibited a cubic shape with enhanced specific surface area (2511 In a recent investigation, Huang and colleagues [85] employed a sonochemical method to synthesize a sheet-like Ln MOF that significantly enhanced the chemiluminescence emission of the NaIO 4 -H 2 O 2 system. The fabricated a Ln MOF exhibited a substantial increase in chemiluminescence, reaching up to 67 times higher intensity.…”

“…Nanomaterials introduced into liquid-phase CL systems generally act as catalysts [35] and luminophores [36,37]. To elucidate the role of Co-MOF and the main light emission species of the system, the CL spectra of the Co-MOF-NaIO 4 -H 2 O 2 system were collected using a transient fluorescence spectrometer.…”

The cobalt metal–organic framework (Co-MOF) is a kind of crystalline porous material within a periodic network structure, which is formed via the self-assembly of a Co metal center and a bridged organic ligand. In this paper, a Co-MOF was facilely synthesized via an ultrasonic method and applied to enhance the chemiluminescence (CL) emission of the NaIO4-H2O2 system. The synthesized Co-MOF was nanosheet-like in nature and stacked in 2–3-micrometer flower shapes. Compared to the NaIO4-H2O2 system without a Co-MOF, the CL intensity of the Co-MOF-NaIO4-H2O2 system was enhanced about 70 times. This CL mechanism was determined to be a result of the synergistic effects of chemiluminescence resonance energy transfer (CRET) and electron–hole annihilation (EHA). The Co-MOF not only acted as a catalyst to accelerate the generation of reactive oxygen species in the CL reaction, but also worked as an emitter to further enhance the CL. Based on the Co-MOF-NaIO4-H2O2 system, a highly sensitive CL analysis method was established for pyrogallol (PG) detection. Addition of PG into the CL system generated 1O2*, which could transfer energy to the Co-MOF and further enhance the CL response. The enhanced CL was linear with the PG concentration. The CL analysis method exhibited a linear range of 1 × 10−4 M to 1 × 10−7 M, as well as having a linear correlation coefficient of 0.9995 and a limit of detection of (S/N = 3) of 34 nM.

“…Metal–organic frameworks (MOFs) are crystalline porous materials formed by metal ions/clusters and organic ligands through coordination bonds . By changing the type and ratio of metal ions/clusters and organic ligands, the structure and properties of the MOFs can be finely tuned. , The distinctive structure endows MOFs with excellent properties, including high porosity, large specific surface area, good thermal stability, and abundant active sites, − making them useful for gas storage, , separation, , catalysis, , drug delivery, and bio/chemical sensing. − Notably, several MOFs, including HKUST-1, iron porphyrin MOF (FePorMOF), and Co-MOF, have been already involved in CL assay, showing excellent catalytic performance in CL reaction. However, most MOFs have bulk stack morphologies, causing too few exposed active sites, which greatly restricts the catalytic activities.…”
