Linear alkanes are essential building blocks for natural and artificial assemblies in water. As compared with typical, linear alkane-based micelles and recent aromatic micelles, we herein develop a cycloalkane-based micelle, consisting of bent amphiphiles with two cyclohexyl frameworks. This uncommon type of micelle, with a spherical core diameter of similar to 2nm, forms in water in a spontaneous and quantitative manner. The cycloalkane-based, hydrophobic cavity displays peculiar host abilities as follows: (i) highly efficient uptake of sterically demanding Zn(II)-tetraphenylporphyrin and rubrene dyes, (ii) selective uptake of substituted Cu(II)-phthalocyanines and spherical nanocarbons, and (iii) uptake-induced solution-state emission of [Au(I)-dimethylpyrazolate](3) in water. These host functions toward the large metal-complex and other guests studied herein remain unaccomplished by previously reported micelles and supramolecular containers.

Cationic fac-[Re(CO)(3)(pz*H)(pypzH)]OTf (pz*H = pyrazole, pzH; 3,5-dimethylpyrazole, dmpzH; indazole, indzH; 3-(2-pyridyl)pyrazole, pypzH) were obtained from fac[ReBr(CO)(3)(pypzH)] by halide abstraction with AgOTf and subsequent addition of the corresponding pyrazole. Successive deprotonation with Na2CO3 and NaOH gave neutral fac[Re(CO)(3)(pz*H)(pypz)] and anionic Na{fac-[Re(CO)(3)(pz*)(pypz)]} complexes, respectively. Cationic fac-[Re(CO)(3)(pz*H)(pypzH)]OTf, neutral complexes fac-[Re(CO)(3)(pz*H)(pypz)], and fac-[Re(CO)(3)(pypz)(2)Na] were subjected to photophysical and electrochemical studies. They exhibit phosphorescent decays from a prevalently (MLCT)-M-3 excited state with quantum yields (F) in the range between 0.03 and 0.58 and long lifetimes (tau from 220 to 869 ns). The electrochemical behavior in Ar atmosphere of cationic and neutral complexes indicates that the oxidation processes assigned to Re-I -> Re-II occurs at lower potentials for the neutral complex compared to cationic complex. The reduction processes occur at the ligands and do not depend on the charge of the complexes. The electrochemical behavior in CO2 saturated media is consistent with CO2 electrocatalyzed reduction, where the values of the catalytic activity [i(cat)(CO2)/i(cat)(Ar)] ranged from 2.7 to 11.5 (compared to 8.1 for fac-[Re(CO)(3)Cl(bipy)] studied as a reference). Controlled potential electrolysis for the pyrazole cationic (3a) and neutral (4a) complexes after 1 h affords CO in faraday yields of 61 and 89%, respectively. These values are higher for indazole complexes and may be related to the acidity of the coordinated pyrazole.

A series of new 9,9-diethylfluorenes consisting of three side-arms each bearing a heterocyclic, bis(carboxymethyl)amino, bis(carbamoylmethyl)amino, bis(ethoxycarbonylmethyl)amino or an amino group were prepared on the basis of 2,4,7-tris(bromomethyl)-9,9-diethylfluorene. Imidazolyl, benzimidazolyl, pyrazolyl, pyrrolyl, 1,3-dioxoisoindolyl and pyridinium groups were taken into account as heterocyclic units, attached to the aromatic skeleton via -CH2-, -CH2NHCH2- or -CH2N=CH- linkers. In addition to the seventeen 2,4,7-trisubstituted 9,9-diethylfluorenes, two macrocyclic compounds were prepared on the basis of 2,7-bis(aminomethyl)-9,9-diethylfluorene. The excellent yield of the macrocyclization reaction is worth a special mention. Both the acyclic and the macrocyclic fluorene-based compounds have, among other things, the potential to act as artificial receptors for different substrates in analogy to the known receptors consisting of a benzene or biphenyl core.

In this study, three triazole based azo molecules [3-amino-4-[1H-1,2,4-triazole-3-yldiazenyl]-1H-pyrazole-5-ol (1), 3-[(3,5-dimethyl-1H-pyrazole-4-yl)diazenyl]-1H-1,2,4-triazole (2) and 4-[1H-1,2,4triazole-3yldiazenyl]benzene-1,3-diol (3)] were, synthesized and characterized by using 1H NMR, FTIR, UV-vis and mass spectra. The molecular structure, vibrational spectroscopic data, electronic transition absorption wavelengths, HOMOs and LUMOs analyses, molecular electrostatic potential (MEP) and potential energy surface (PES) diagrams were calculated by using DFT/B3LYP method with 6-311G(d,p) basis set. NMR chemical shift calculations were performed by using the gauge-invariant atomic orbital (GIAO) method. The spectroscopic results obtained from quantum chemical calculations of the 1, 2 and 3 molecules were in good agreement with the experimental data. Antibacterial activities of the 1, 2 and 3 were investigated against four different bacterial cultures. Although 1 molecule did not show very good antibacterial activity, 2 and 3 showed good activity against Staphylococcus aureus at a MIC of 250 and 62.5 mg/mL, respectively. Druglikeness and some of the pharmacokinetic properties of the 1, 2 and 3 were also examined. In addition, molecular docking studies were performed to investigate the antibacterial properties of synthesized compounds by in silico method. For this purpose, beta-ketoacyl-acyl carrier protein (ACP) synthase III (KAS III) and lipoteichoic acid synthase (LtaS) inhibitory properties of 1, 2 and 3 molecules were investigated. Although all of the synthesized compounds showed antibacterial properties according to the results of the molecular docking studies, the best results were obtained by the compound 3 which interacts with both KAS III and LtaS with binding energy of -7.17 and -7.53 kcal/mol, respectively.

The direct reaction of a series of substituted (1H-pyrazol-1-yl)pyridazine (L-I: 6-(1H-pyrazolyl)pyridazine; L-II: 3-chloro-6-(1H-pyrazole-1-yl)-pyridazine; L-III: 6-(1H-3,5-dimethylpyrazolyl)pyridazine-3-carboxylic acid; L-IV: 3,6-bis-N-pyrazolyl-pyridazine; and L-V: 3,6-bis-N-3-methylpyrazolyl-pyridazine) with the bromotricarbonyl(tetrahydrofuran)rhenium(I) dimer leads to the monometallic complexes [(L-X)Re(CO)(3)Br] (I-V), which displays a nonregular octahedral geometry around the Re-I center and a fac-isomerism for the carbonyl groups, whereas pyridazine and pyrazolyl rings remain highly coplanar after coordination to rhenium. Cyclic voltammetry shows one irreversible oxidation and one irreversible reduction for each compound as measured in N, N-dimethylformamide. Oxidation ranges from 0.94 V for III to 1.04 V for I and have been attributed to the Re-I/Re-II couple. In contrast, the reductions are ligand centered, ranging from -1.64 V for II to -1.90 V for III and V. Density functional theory calculations on the vertical one electron oxidized and one electron reduced species, using the gas-phase optimized geometry for the neutral complex confirm this assignment. Compounds I-V show two absorption bands, one around 410 nm (metal-to-ligand charge transfer (MLCT), Re-d pi -> pi*) and the other at similar to 300 nm (intraligand, pi -> pi*). Excitation at 400 nm at 77 K leads to unstructured and monoexponential emission with large Stokes shift, whose maxima vary between 570 (III) and 636 (II) nm. The quantum yields for these emissions in solution are intensified strongly going from air to argon equilibrated solution. Singlet oxygen quantum yields change from 0.03 (III) to 0.21 (IV). These data are consistent with emission from (MLCT)-M-3. The emission undergoes a bathochromic shift when R-1 is a pi-donating group (Cl or N-pyrazolyl) and a hypsochromic shift for a pi-acceptor (COOH). The bimolecular emission quenching rate constant by triethylamine (TEA) for II, IV, and V is 1.09, 0.745, and 0.583 x 10(8) M-1 s(-1), respectively. Photolysis in dichloromethane-CO2 saturated solution with TEA as a sacrificial electron donor leads in all cases to formic acid generation.

A series of pyrazolylimine CoCl2 complexes were synthesized and well characterized. The single crystal structures and coordination geometries of these complexes were confirmed by X-ray diffraction, which revealed dimeric and monomeric structures, and thereby distorted trigonal bipyramidal and distorted tetrahedral geometries, respectively. In combination with diethylaluminum chloride (DEAC) and methylaluminoxane (MAO) as cocatalysts, the present cobalt complexes displayed high activity toward isoprene polymerization, affording cis-1,4/3,4-polyisoprenes. Polymerization parameters have significant influence on the polymerization behavior. Additionally, incorporation of the external donor triphenylphosphine led to a switch in selectivity of the system from cis-1,4 to 3,4, providing an effective method to adjust the 3,4-moieties on a large scale.
