Lanthanide Metal-Organic Frameworks as Luminescent Sensor for Toluene

Paving the Way for a Green Transition in the Design of Sensors and Biosensors for the Detection of Volatile Organic Compounds (VOCs)

“…In previous years, different lanthanide complexes have been reported as simple, sensitive, and inexpensive analytical tools for the determination of many organic solvents, metal ions and in general gases due to their structural and unique luminescent properties. Very recently, they have been also proved to be usable as sustainable sensors for the specific detection of toluene [ 101 ]. In details a new sequence of lanthanide metal-organic frameworks (LnMOFs) was prepared though a simple and inexpensive solvothermal reaction, using lanthanide (III) nitrates, methylmalonic acid as the ligand and 1,10-phenanthroline as the capping agent.…”

Effect of Different Synthesis Approaches on Structural and Thermal Properties of Lanthanide(III) Metal–Organic Frameworks Based on the 1H-Pyrazole-3,5-Dicarboxylate Linker

“…Coordination polymers based on the lanthanide ions offer not only extremely intriguing topological architectures arising from high and variable coordination number but also a wide range of potential applications derived from their extraordinary magnetic and luminescence properties. These characteristics make them very attractive materials in many advanced technologies such as photonics and optoelectronics, chemical sensing, catalysis and energy storage [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. An important factor in the strategy of coordination polymer construction is the selection of an organic ligand with the appropriate functional groups which will be able to coordinate metal centers and form bridges among them.…”

“…Huge numbers of carboxylic acids with aromatic, aliphatic or heterocyclic moieties are used as linkers in the lanthanide coordination polymers because of great affinity of carboxylate oxygen donor atoms for lanthanides. Particularly ligands containing more than one carboxylate group have drawn great interest due to more coordination sites and great tendency towards creation of multidimensional polymeric structures [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. Besides benzenepolycarboxylic acids, which are regarded as the most explored linkers, multicarboxylic acids based on the rigid heterocyclic aromatic rings such as: pyridine, pyrazole, thiophene or furane are regarded as very attractive ligands in the formation of coordination polymers [35][36][37][38][39][40].…”
