Luminescent thermometer based on Eu3+/Tb3+-organic-functionalized mesoporous silica

In this work we investigate a mesoporous silica (MS) decorated with dipyridyl-pyridazine (dppz) ligands and further grafted with a mixture of Eu3+/Tb3+ ions (28.45%:71.55%), which was investigated as a potential thermometer in the 10-360K temperature range. The MS material was prepared employing a hetero Diels-Alder reaction: 3,6-di(2-pyridyl)-1,2,4,5-tetrazine was reacted with the double bonds of vinyl-silica (vSilica) followed by an oxidation procedure. We explore using the dppz-vSilica material to obtain visible emitting luminescent materials and for obtaining a luminescent thermometer when grafted with Eu3+/Tb3+ ions. For the dppz-vSilica@Eu,Tb material absolute sensitivityS(a) of 0.011K(-1) (210K) and relative sensitivityS(r) of 1.32 %K-1 (260K) were calculated showing good sensing capability of the material. Upon temperature change from 10K to 360K the emission color of the material changed gradually from yellow to red.

Static second hyperpolarizability of inverse sandwich compounds (M-1-C5H5-M-2) of alkali (M-1 = Li, Na, K) and alkaline earth metals (M-2 = Be, Mg, Ca)

In the investigated inverse sandwich complexes, charge transfer from alkali metal (M1) led to aromatically stabilized Cp ring, which prevented further charge transfer from the alkaline earth metal (M2). This electron push effect resulted in diffusion of electron density from the outermost ns” subshell of alkaline earth metal. The alkaline earth metal is weakly bound to the alkali metal-C5H5 complex. The vertical ionization energy of the chosen M1-Cp-M2 complexes was smaller than that of the corresponding alkaline earth metals. Large second hyperpolarizability (106-108 a. u.) was obtained for the studied molecules. The correction due to the basis set superposition error (BSSE) in the calculated second hyperpolarizability was found to be small for larger systems, while it was rather significant for small systems. The MP4SDQ and CCSD results were in fair agreement, which indicates the necessity of higher order electron correlation treatment in the accurate description of second hyperpolarizability. Calculated dynamic second hyperpolarizabilities at 1064 nm were found to increase considerably for most of the chosen metal complexes.

Click Chemistry Derived Pyridazines: Electron-Deficient Building Blocks with Defined Conformation and Packing Structure

A series of 3,6-bis(4-triazolyl)pyridazines equipped with terminal phenyl substituents with varying degree of fluorination were synthesized by using the facile copper-catalyzed azide-alkyne cycloaddition and their structures were thoroughly investigated in the gas phase, in solution, and in the solid state by employing DFT calculations, NMR spectroscopy, and single-crystal X-ray diffraction, respectively. On the molecular level, their structure is governed by the strong preference of the triazole-pyridazine linkages for the anti-conformation. The supramolecular organization of the molecules in the crystalline solid is controlled by -stacking, C-H as well as C-FH interactions. The latter can conveniently be tuned by the number and position of fluorine substituents in the terminal phenyl units, giving rise to either herringbone-like, 1D or 2D lamellar packing. Electrochemistry and optical spectroscopy of all compounds suggest that they might find use as electron-transporting/hole-blocking materials in organic electronics.

Tunable Optical and Photocatalytic Properties of Low-Dimensional Copper(I)-Iodide Hybrids Using Coordinating Organic Ligands

A family of copper(I)-iodide/organic hybrid compounds was investigated for the impact of coordinating organic ligands on their structures, as well as on their optical and photocatalytic properties. This included the synthesis of two new crystalline compounds, [(CuI)(2) (bpmd)] and [(CuI)(2) (bpp)] (bpmd = 2,2′-bipyrimidine, bpp = 2,3-bis(2-pyridyl)pyrazine), both of which consist of chain structures formed by (CuI)(2) rhombus-shaped dimers that are further coordinated to the Ngroups of the bridging organic ligands. To more broadly investigate structure-property relationships within this system, nine related copper(I)-iodide/organic hybrid compounds, that is, [(CuI)(2)L-n] (n = 1 or 2; L = 1,2-bis(4-pyridyl) ethylene (bpe); 2,2’bipyrimidine (bpmd); 2,3-bis(2-pyridyl) pyrazine (bpp); 4,4′-bipyridine (44bpy); pyridazine (pdz); pyrimidine (pmd); pyrazine (pz); pyrazinamide (pza); quinoxaline (quin)) were also prepared in high purity containing extended (CuI)(infinity) chains or sheets coordinated to bridging or terminating organic ligands. The optical absorption edges of all hybrid compounds were measured using UV-vis diffuse reflectance spectroscopy. Incorporation of the organic ligand functions to significantly decrease the bandgap size with respect to the parent gamma-CuI (E-g = 3.1 eV = optical band gap) into the visible-light wavelengths spanning from similar to 1.7 to , similar to 2.6 eV for the [(CuI)(2)L-n] family. Their optical bandgap sizes were found to be controlled specifically by the framework density, the number of N atoms bonded to each Cu atom, and the number of N atoms in each heterocyclic ring within the ligands. Their photocatalytic properties were investigated and found to show high activity for the light-driven degradation of methylene blue, for example, degrading as fast as within similar to 20 min for [(CuI)(pza)]. These photocatalytic activities were found to be related to the orbital energies of the Cu 3d(10) and I 5p(6) relative to that of the organic ligands, as well as to the local and extended connectivity of their crystalline structures. In contrast to the instability of other metal halide compounds, for example, lead-based halide perovskites, all copper(I)-iodide hybrids were found to be stable within aqueous solutions while under irradiation by ultraviolet and visible light. These results demonstrate the stability and photocatalytic activity copper(I)-iodide/organic hybrids in light-driven redox reactions.

Selectivity and Physicochemical Optimization of Repurposed Pyrazolo[1,5-b]pyridazines for the Treatment of Human African Trypanosomiasis

From a high-throughput screen of 42 444 known human kinases inhibitors, a pyrazolo[1,5-b]pyridazine scaffold was identified to begin optimization for the treatment of human African trypanosomiasis. Previously reported data for analogous compounds against human kinases GSK-3 beta, CDK-2, and CDK-4 were leveraged to try to improve the selectivity of the series, resulting in 23a which showed selectivity for T. b. brucei over these three human enzymes. In parallel, properties known to influence the absorption, distribution, metabolism, and excretion (ADME) profile of the series were optimized resulting in 20g being progressed into an efficacy study in mice. Though 20g showed toxicity in mice, it also demonstrated CNS penetration in a PK study and significant reduction of parasitemia in four out of the six mice.

Construction of Unusual Indole-Based Heterocycles from Tetrahydro-1H-pyridazino[3,4-b]indoles

Herein, we report the successful syntheses of scarcely represented indole-based heterocycles which have a structural connection with biologically active natural-like molecules. The selective oxidation of indoline nucleus to indole, hydrolysis of ester and carbamoyl residues followed by decarboxylation with concomitant aromatization of the pyridazine ring starting from tetrahydro-1H-pyridazino[3,4-b]indole derivatives lead to fused indole-pyridazine compounds. On the other hand, non-fused indole-pyrazol-5-one scaffolds are easily prepared by subjecting the same C2,C3-fused indoline tetrahydropyridazines to treatment with trifluoroacetic acid (TFA). These methods feature mild conditions, easy operation, high yields in most cases avoiding the chromatographic purification, and broad substrate scope. Interestingly, the formation of indole linked pyrazol-5-one system serves as a good example of the application of the umpolung strategy in the synthesis of C3-alkylated indoles.
