In the current work, we present the use of two free-base and two zinc-metallated porphyrin-ruthenium(II) polypyridine dyads, along with two reference porphyrin derivatives, as sensitizers in both nand p-type DSSCs and DSPECs. Two of the dyads contain the well-known Ru(bpy)(3) unit (HOOC-DMP-Ru(bpy)(3) and HOOC-(Zn)DMPRu(bpy)(3)), while in the other two terpyridine-Ru(Cl)-bypiridine was used (HOOC-DMP-tpy-Ru and HOOC-(Zn) DMP-tpy-Ru). In all systems, the amide-bonding motif was utilized for the connection of the counterparts comprising each dyad. Photophysical investigation of the reported systems indicated sufficient electronic interactions for the dyads in their excited states (emission measurements). The photovoltaic measurements revealed that the presence of the ruthenium complex improves the overall performance of the dyads with the most efficient dyad being HOOC-(Zn)DMP-tpy-Ru in both nand p-type DSSCs. Consequently, HOOC-(Zn)DMPtpy-Ru was used to fabricate nand p-DSPECs towards the oxidation of methoxy-benzyl alcohol and the reduction of CO2, respectively.

An air-stable Mg salt, [Mg(MIm)(6)][TFSA](2) [MIm = 1-methylimidazole; TFSA = bis(trifluoromethylsulfonyl)amide], was obtained by recrystallization from the MIm solution of Mg[TFSA](2). This compound melts at 481 K under sealed conditions, whereas it loses MIm at elevated temperatures (448 K, 5% weight loss) under unsealed conditions. The crystal structure of [Mg(MIm)(6)][TFSA](2) was determined by X-ray diffraction. The compound crystallizes in the monoclinic system (space group P2(1)/c) with a = 8.2062(7) angstrom, b = 11.3185(10) angstrom, c = 24.454(2) angstrom, = 90.229(2)degrees, V = 2271.3(3) angstrom(3), and Z = 2. The Mg2+ cation is octahedrally surrounded by six non-methylated N atoms of MIm ligands to form the [Mg(MIm)(6)](2+) complex cation, in which three imidazolium rings are crystallographically independent. The interplanar angles between two imidazolium rings, which are close to 90 degrees in an ideal model, are 64.01(14), 72.86(18), and 81.91(17)degrees owing to the interaction of the [Mg(MIm)(6)](2+) cations with the TFSA(-) anions. The TFSA anion is completely isolated from the Mg2+ core and adopts the energetically favorable trans conformation. Raman spectroscopic measurements revealed the octahedral coordination of MIm to Mg2+ in crystalline [Mg(MIm)(6)][TFSA](2) and MIm solutions of Mg[TFSA](2).

The quaternary-ammonium-salt-type amphiphilic compounds 3C(n)tris-s-Q X (star-type; carbon number between the central amino and ammonium groups s = 2, 3) and 3C(n)lin-3-Q X (linear-type; carbon number between the hydrophilic groups s = 3), where n represents the alkyl chain length (n = 8, 10, 12, 14) and X represents a counterion [hexafluorophosphate, trifluoromethanesulfonate (OTf), bis(fluorosulfonyl)amide (FSA), and bis(trifluoromethanesulfonyl)amide (NTf2)], were synthesized. Except for 3C(12)tris-3-Q OTf, these trimeric compounds presented melting points lower than 100 degrees C and therefore are defined as ionic liquids. Among them, 3C(n)tris-3-Q NTf2 (n = 8, 12, 14) and 3C(n)lin-3-Q NTf2 (n = 8, 10) presented melting points lower than 0 degrees C. The melting points of the amphiphilic trimeric ionic liquids (n = 8, 10), which were lower for the star- than for the linear-type compounds, were higher than those of the corresponding monomeric compounds but lower than those of the corresponding gemini samples. Moreover, the amphiphilic trimeric ionic liquids exhibited higher conductivities and lower viscosities than the corresponding gemini ionic liquids, while the star-type trimeric ionic liquids presented lower conductivities and higher viscosities than those of the linear-type compounds. The amphiphilic trimeric ionic liquids also readily adsorbed at the air/water interface and oriented themselves to form micelles in aqueous solution. This aggregation behavior was not observed in the monomeric and gemini ionic liquids.

Quantum-chemical calculations have been performed for twenty-one favored and rare isomers of neutral isocytosine in two extreme media, in the gas phase {B3LYP/6-311+G(d,p)} and in aqueous solution {PCM (water)//B3LYP/6-311+G(d,p)}. In aqueous solution, the most aromatic hydroxy-amino form, favored in the gas phase, becomes a rare form, and less delocalized amino-oxo forms predominate. Monoprotonation of the favored isomers leads also to two different forms, the N1-protonated hydroxy-amino cation in the gas phase, and the N1-protonated amino-oxo cation in aqueous solution. Electron delocalization for the solvated isocytosine isomers is parallel to that observed for the isolated molecules. However, aromaticity is not the main factor that influences isomeric stabilities. Geometric and energetic results for neutral isocytosine isomers, compared to those for other pyrimidine bases (uracil and cytosine), show interesting similarities in electron delocalization and important differences in energetic stabilities. Some parallelism in energetic parameters exists for amine-imine and enamineimine conversions, and separately for amide-iminol and keto-enol ones. (C) 2017 Elsevier B.V. All rights reserved.

The current study aims to assign and estimate the total creatine (tCr) signal contribution to the Z-spectrum in mouse brain at 11.7 T. Creatine (Cr), phosphocreatine (PCr) and protein phantoms were used to confirm the presence of a guanidinium resonance at this field strength. Wild-type (WT) and knockout mice with guanidinoacetate N-methyltransferase deficiency (GAMT-/-), which have low Cr and PCr concentrations in the brain, were used to assign the tCr contribution to the Z-spectrum. To estimate the total guanidinium concentrations, two pools for the Z-spectrum around 2 ppm were assumed: (i) a Lorentzian function representing the guanidinium chemical exchange saturation transfer (CEST) at 1.95 ppm in the 11.7-T Z-spectrum; and (ii) a background signal that can be fitted by a polynomial function. Comparison between the WT and GAMT-/-mice provided strong evidence for three types of contribution to the peak in the Z-spectrum at 1.95 ppm, namely proteins, Cr and PCr, the latter fitted as tCr. A ratio of 20 +/- 7% (protein) and 80 +/- 7% tCr was found in brain at 2 mu T and 2 s saturation. Based on phantom experiments, the tCr peak was estimated to consist of about 83 +/- 5% Cr and 17 +/- 5% PCr. Maps for tCr of mouse brain were generated based on the peak at 1.95 ppm after concentration calibration with in vivo magnetic resonance spectroscopy.

Main conclusion Excited state lifetime-based separation of fluorophore-tagged antibiotic conjugate emission from the spectrally broad plant autofluorescence enables in planta tracking of the translocation of systemic cargo such as antibiotics via fluorescence lifetime imaging. The efficacy of antibiotic treatments in citrus crops is uncertain due to mixed results from in-field experiments and a lack of study on their systemic movement. As of yet there has been an inability to track treatments using traditional fluorescence microscopy due to treatments having little fluorescence characteristics, and signal convolution due to plant autofluorescence. In this study, we used streptomycin sulfate, a commercially available antibiotic, and conjugated it to a modified tris(bipyridine) ruthenium (II) chloride, a dye with an excited state lifetime magnitudes higher than other commonly used organic fluorescent probes. The resultant is a fluorescence lifetime imaging (FLIM) trackable antibiotic conjugate, covalently attached via an amide linkage that is uniquely distinguishable from plant autofluorescence. Characterization of the fluorescent antibiotic conjugate showed no mitigation of excited state lifetime, and a distinct IR peak not found in any synthetic components. Subsequent tracking using FLIM in citrus tissue was achieved, with identification of movement through citrus plant vasculature via tissue localization in xylem and phloem. Results indicated upwards systemic movement of the conjugate in both xylem and phloem after 48 h of incubation. However, the conjugate failed to move down towards the root system of the plant by 168 h. Mechanistically, it is likely that xylem contributes heavily in the translocation of the conjugate upwards; however, phloem led flow due to growth changes could act as a contributor. This proof-of-concept sets groundwork for subsequent studies regarding antibiotic localization and movement in citrus.

Terminal silanol groups on the glass surface were used for the chemical bonding of a-bromo amide as the initiator for surface initiated Cu(0)-mediated living radical polymerization (LRP) to graft well-defined poly(butyl arylate) (PBA) and poly(2,2,2-trifluoroethyl methacrylate) (PTFEM) brushes on the glass surface. A grafting to methodology was also performed by the modification of the glass surface using a thiosilane agent and performing a thio-bromo click reaction in the presence of PBA and PTFEM synthesized via Cu(0)-mediated LRP. Furthermore, a one-pot grafting to method was developed that proved a facile, fast, and efficient method for grafting a bromo-terminated polymer to the glass surface in one step. All glass slides were characterized using ATR-FTIR and UV-vis spectroscopy, water contact angle measurements and SEM. The surface topology and roughness of selected samples were analyzed using AFM. Results show that an ultrathin layer of a polymer with nanoscale features and high roughness was chemically grafted to the glass surface without compromising glass transparency. These methodologies can be used to graft well-defined polymers with different functionalities on the glass surface.
