Luminescence modulation, near white light emission, selective luminescence sensing, and anticounterfeiting via a series of Ln-MOFs with a π-conjugated and uncoordinated lewis basic triazolyl ligand

Abstract

A series of Ln-MOFs with π-conjugated and uncoordinated lewis basic triazolyl ligand have luminescence modulation, near white light emission, selective luminescence sensing, and anticounterfeiting.

Lanthanide-based metal–organic framework materials as bifunctional fluorescence sensors toward acetylacetone and aspartic acid

“…18,19 In particular, the photoluminescence characteristics of Ln-MOFs expand the application in molecular switches and chemical sensors. 10–24 Many Ln-MOFs have been applied to detect metal cations, inorganic anions and small organic molecules. 25,26 However, there are few reports of Ln-MOFs for the detection of amino acids.…”

The Chemistry and Applications of Metal–Organic Frameworks (MOFs) as Industrial Enzyme Immobilization Systems

“…Luminescence, another key property, is characterized by the emission of light from the excited compounds. In MOFs, this is not only associated with the type of metal present in their composition but can be potentialized by organic ligands that present ideal chromophores for this property, such as aromatic structures [ 164 , 165 ].…”

A multicolor-switchable fluorescent lanthanide MOFs triggered by anti-cancer drugs: multifunctional platform for anti-cancer drug sensing and information anticounterfeiting

“…5 But to date, it is extremely rare to apply a kind of Ln-MOFs material, which can realize the dual-functionality of both fluorescent anticounterfeiting and fluorescent sensing based on the same fluorescence response mechanism. 1 a ,6 In fact, the high quantum yield, fluorescence-adjustable properties, and visible fluorescence responses make Ln-MOFs, a promising candidate to realize simultaneously a chemical sensing platform and an anticounterfeiting security system. 7 The above prompted us to explore appropriate Ln-MOFs materials, which can satisfy the expectation to apply in both fluorescent anticounterfeiting and fluorescent sensing at the same time.…”
