A Novel Fluorescent Chemosensor Assembled with 2,6-Bis(2-Benzimidazolyl)Pyridine-Functionalized Nanoporous Silica-Type SBA-15 for Recognition of Hg2+ Ion in Aqueous Media

A novel fluorescent sensor for the recognition of Hg2+ in aqueous media was developed by assembly of 2,6-bis(2-benzimidazolyl) pyridine to SBA-15 nanoporous silica. The synthesized materials were characterized by techniques such as XRD, FT-IR, N2 adsorption?desorption, and TGA. Investigation of fluorescence properties of prepared material revealed emission spectra having maxima at 396 nm following excitation at 353 nm. It was found that the fluorescence intensity of the SBA-15 functionalized material remarkably quenched in the presence of Hg2+ ions in the pH range of 6?8, showing high selectively toward mercury ion among the more common tested cations. The fluorescence titration studies confirmed the linear relation between the concentration of Hg2+ ion and the fluorescence intensity quenching, and the lowest detection limit was calculated as 2.6 × 10?6 M.

Photoactivatable CO-Releasing Properties of {Ru(CO)2}-Core Pyridylbenzimidazole Complexes and Reactivity towards Lysozyme

The photoinduced CO-releasing properties of [RuLPy(CO)2Cl2] (1), [Ru(LPy2Bz-?2N1,N2)(CO)2Cl2] (2), and [Ru(LPy2Bz?Et-?3N1,N2,N3)(CO)2(Cl)]·PF6 (3) [LPy = 2-(2-pyridyl)benzimidazole, LPy2Bz = 2,6-bis(benzimidazole-2?-yl)pyridine, and LPy2Bz?Et = 2,6-bis(1-ethyl-benzimidazol-2?-yl)pyridine] in both DMSO and reduced myoglobin solution are reported. Complexes 1 and 2 release CO upon illumination at 365 nm. The bidentate chelation mode of LPy2Bz in 2 is changed into a meridional tridentate mode upon the ethylation of the benzimidazolic NH groups, 3. The extension of the conjugation system and the shift of the MLCT band into the visible region in 3 give rise to the RuII dicarbonyl complex capable of releasing CO at 468 nm. During illumination of 2, the chelation mode of LPy2Bz is changed from ?2N1,N2 to ?3N1,N2,N3, as monitored by solution NMR spectroscopic studies. The spectral properties were studied by TD-DFT calculations. The interaction of 1?3 with hen-egg-white lysozyme, as a biocompatible carrier, has been studied by ESI-MS and UV/Vis spectroscopy in the dark and upon illumination. Stable protein adducts containing the RuII(CO)2 moiety, capable of photoinduced release of CO, are formed.

Synthesis of pyridine-based poly(N-arylenebenzimidazole sulfone)

Poly(N-arylenebenzimidazole pyridine sulfone) (PNABIPS) has been prepared via the aromatic nucleophilic displacement reaction of 2,6-bis(2-benzimidazoly) pyridine (BBP) with bis(4-fluorophenyl) sulfone. BBP was synthesized by reaction of 2,6-pyridinedicarboxylic acid with 1,2-phenylenediamine in polyphosphoric acid. The chemical structure of BBP was confirmed by FT-IR, HRMS, 1H NMR and 13C NMR. The characterization of the polymer was performed with FT-IR, 1H NMR, elemental analysis, GPC, XRD, DSC, TGA and solubility tests. The polymer was obtained in quantitative yield with M n value 12,600 and Mw value 28,300, respectively. DSC and TGA measurements show that the glass transition temperature (Tg) is 312 C and 5% weight loss temperature is 434C in nitrogen and 545C in air, respectively. In addition, the novel polymer exhibits good solubility, which can be dissolved in common organic solvent at room temperature.

Separation of lanthanides and actinides(III) using tridentate benzimidazole, benzoxazole and benzothiazole ligands

The ability of new hydrophobic tridentate ligands based on 2,6-bis(benzimidazol-2-yl)pyridine, 2,6-bis(benzoxazol-2-yl)pyridine and 2,6-bis(benzothiazol-2-yl)pyridine to selectively extract americium(III) from europium(III) was measured. The most promising ligand – 2,6-bis(benzoxazol-2-yl) -4-(2-decyl1-tetradecyloxy)pyridine L9 was found to give separation factors (SFAm/Eu) of up to 70 when used to extract cations from 0.02-0.10 M HNO3 into TPH in synergy with 2-bromodecanoic acid. Six structures of lanthanide complexes with 2,6-bis(benzoxazol-2-yl)pyridine L 6 were then determined to evaluate the types of species that are likely to be involved in the separation process. Three structural types were observed, namely [LnL6(NO3)3(H 2O)2], 11-coordinate only for La, [LnL6(NO 3)3 (CH3CN)], 10-coordinate for Pr, Nd and Eu and (LnL6(NO3)3(H2O)], L 10-coordinate for Eu and Gd. Quantum Mechanics calculations were carried out on the tridentate ligands to elucidate the conformational preferences of the ligands in the free state and protonated and diprotonated forms and to assess the electronic properties of the ligands for comparison with other terdentate ligands used in lanthanide/actinide separation processes.

Resistance Controllability in Alkynylgold(III) Complex-Based Resistive Memory for Flash-Type Storage Applications

Owing to the demands of state-of-the-art information technologies that are suitable for vast data storage, the necessity for organic memory device (OMD) materials is highlighted. However, OMDs based on metal complexes are limited to several types of transition-metal complex systems containing nitrogen-donor ligands. Herein, attempts are made to introduce novel alkynylgold(III) materials into memory devices with superior performance. In this respect, an alkynyl-containing coumarin gold(III) complex, [(C19N5H11)Au?C?C?C9H5O], has been synthesized and integrated into a sandwiched Al/[(C19N5H11)Au?C?C?C9H5O]/indium tin oxide device. By precisely controlling the compliance current (Icc), the devices show different switching characteristics from flash-type binary resistance switching (Icc?10?3 A) to WORM-type (WORM=write once read many times) ternary resistance switching (Icc=10?2 A). This work explores electrical gold(III) complex based memories for potential use in organic electronics.

Bonding and charge transfer in nitrogen-donor uranyl complexes: Insights from nexafs spectra

We investigate the electronic structure of three newly synthesized nitrogen-donor uranyl complexes [(UO2)(H2bbp)Cl2], [(UO)2(Hbbp)(Py)Cl], and [(UO2)(bbp)(Py)2] using a combination of near-edge X-ray absorption fine structure (NEXAFS) spectroscopy experiments and simulations. The complexes studied feature derivatives of the tunable tridentate N-donor ligand 2,6-bis(2-benzimidazyl)pyridine (bbp) and exhibit discrete chemical differences in uranyl coordination. The sensitivity of the N K-edge X-ray absorption spectrum to local bonding and charge transfer is exploited to systematically investigate the evolution of structural as well as electronic properties across the three complexes. A thorough interpretation of the measured experimental spectra is achieved via ab initio NEXAFS simulations based on the eXcited electron and Core-Hole (XCH) approach and enables the assignment of spectral features to electronic transitions on specific absorbing sites. We find that ligand-uranyl bonding leads to a signature blue shift in the N K-edge absorption onset, resulting from charge displacement toward the uranyl, while changes in the equatorial coordination shell of the uranyl lead to more subtle modulations in the spectral features. Theoretical simulations show that the flexible local chemistry at the nonbinding imidazole-N sites of the bbp ligand is also reflected in the NEXAFS spectra and highlights potential synthesis strategies to improve selectivity. In particular, we find that interactions of the bbp ligand with solvent molecules can lead to changes in ligand-uranyl binding geometry while also modulating the K-edge absorption. Our results suggest that NEXAFS spectroscopy combined with first-principles interpretation can offer insights into the coordination chemistry of analogous functionalized conjugated ligands.

Ti, Zr and v complexes with N-allyl functionalized heterocyclic ligands as catalysts for ethylene polymerization Dedicated to Professor Max Herberhold on the occasion of his 80th birthday (August 02, 2016).

Titanium, zirconium and vanadium complexes with N-allyl functionalized 1,2-bis(benzimidazolyl)benzene, 1,2-bis(benzimidazolyl)ethane, 1,1-bis(benzimidazolyl)methane, 2,2-bis(benzimidazolyl), 2,6-bis(benzimidazolyl)pyridine and 2-(benzimidazolyl)pyridine ligands were synthesized and characterized. After activation with methylaluminoxane (MAO) they were applied for catalytic ethylene polymerization. The performance of such homogeneous catalysts is unique: they have high activities (up to 3278 kg PE/mol cat h), they produce bimodal or multimodal resins with high molecular weights and they have the potential to produce their own support for heterogeneous polymerization reactions. Such catalysts combine all features for single-reactor bimodal polyethylene technology.
