“…It can be seen that the photoluminescence spectrum of the title complex (1) shown that it has an effective absorption in the range of 200-300 nm with two peaks located at 655 nm and 710 nm, which can be ascribed to 4 F9/2→ 4 I15/2 and 4 I11/2→ 4 I15/2, respectively. [31][32][33][34][35] When excited under 264 nm, it exhibits two emission bands in the range of 625-750 nm with the peak values being 655 nm and 710 nm, respectively. The strongest emission band of the title complex (1) is in the red light region, so the title complex (1) is possibly a red light emitting material.…”

A novel one-dimensional erbium complex [ErL2(NO3)(H2O)2]n (HL = 2-picolinic acid) was synthesized by hydrothermal methods, and its crystal structure was determined by single crystal x-ray diffraction. The complex crystallize in monoclinic system, space group C2/c with a = 15.7525(5) Å, b = 11.4958(4) Å, c = 9.7977(3) Å, β = 102.862(3) º, V = 1729.72(10) Å3, C12H10ErN3O9, Mr = 507.49, Z = 4, Dc = 1.949 g•cm-3, F(000) = 972,  = 4.901 mm-1, S= 1.119, λ(MoKα) = 0.071073 nm, R = 0.0239 and wR = 0.0668. The 2-picolinic acid ligand adopts bidentate bridging coordination mode to connect adjacent erbium ions to form a one-dimensional chain structure. A series of properties of the complex were measured by solid-state photoluminescence, solid-state diffuse reflection and differential scanning calorimetry.

“…The photocatalytic activity of MOF was enhanced by adding modulator compounds like isonicotinic acid. Isonicotinic acid is a pyridine carboxylate compound that can be an excellent linker to construct coordination complexes [10]. Garibay et al [11] reported that the addition of isonicotinic acid increases MOFs' size and pore volume and enhances their catalytic activity.…”

Isonicotinic acid is a pyridine carboxylic compound that can be used as a linker to construct coordination complexes. Adding isonicotinic acid (HIna) to the metal-organic framework (MOF) enhanced the MOF surface area, pore volume, and pore size and increased its catalytic activity. Ti3C2Tx MXene nanosheet with excellent metal conductivity was also employed on MOF to optimize its functionality. This work aims to synthesize MOF modulated isonicotinic acid La-PTC-HIna and design the new materials: La-PTC/Ti3C2Tx MXene and La-PTC-HIna/Ti3C2Tx MXene hybrid, then apply them for methylene blue photodegradation. La-PTC-HIna, La-PTC/Ti3C2Tx MXene, and La-PTC-HIna/Ti3C2Tx MXene were synthesized by the sonochemical method. MOF La-PTC-HIna has the highest methylene blue photocatalytic degradation activity than MOF La-PTC, Ti3C2Tx MXene, La-PTC/Ti3C2Tx MXene, and La-PTC-HIna/Ti3C2Tx MXene with degradation efficiency of 99.48% in 20 ppm methylene blue under visible irradiation for 210 min. This study reveals the La-PTC-HIna and La-PTC-HIna/Ti3C2Tx MXene as a new material that has the potential to remove methylene blue from an aqueous solution.

“…Among various coordination networks, luminescent CPs have been extensively investigated and are usually employed for sensing specific targeted metal ions, inorganic anions, or organic molecules for environmental protection and human health. − These inorganic–organic hybrid sensors can be superior to other luminescent materials due to their designable structures, structural flexibilities, and tunable chemical and physical properties. − Taking advantage of these unique merits, a large number of light-emitting CP-based chemical sensors have been developed for probing hazardous chemicals, including explosives and ionic pollutants, according to fluorescence quenching (turn-off) or the fluorescence shift mechanism. , For instance, Li and co-workers reported a porous blue-light-emitting LMOF-241 that showed a high “turn-off” response to Aflatoxin B1 at a level of parts per billion, which can be considered a superb luminescence-based chemical sensor . The luminescent metal–organic frameworks (MOFs) synthesized by Plakatouras et al, i.e., MOR-1 and MOR-2, are capable of luminescence sensing toward ReO 4 – with a high efficiency and selectivity, which was demonstrated for the first time among CP materials .…”

Using a pyridine-derived molecule 1,3,5-tris(4-pyridyl)benzene (TPB) and a polycarboxylate linker 1,3-benzenedicarboxylic acid (H2BDC), a Co(II)-based coordination polymer {[Co(TPB)(BDC)]·0.5H2O} (1) with a high water stability was successfully prepared and fully characterized. Compound 1 possesses a unique 3D pillar-chained network wherein the adjacent 1D double [Co(BDC)] chains are further connected by TPB pillars. The photoluminescence property of 1 was studied, exhibiting a weak emission with UV light irradiation. Interestingly, the multiresponsive luminescence makes compound 1 a versatile chemosensor for several metal cations and inorganic anions in aqueous solutions. It has a great ability to selectively detect cationic Al3+ and Cu2+ and anionic IO4 – through luminescence turn-on or turn-off effects. In particular, the luminescence intensity could be significantly decreased by existence of IO4 –, which is seldom reported among the cobalt-based coordination polymers and implies that 1 can act as an effective fluorescence probe to sense corresponding species. The quenching mechanism for various ions has been discussed in detail. In addition, the magnetic property of 1 was investigated.
