Lithium?sulfur batteries are a major focus of academic and industrial energy-storage research due to their high theoretical energy density and the use of low-cost materials. The high energy density results from the conversion mechanism that lithium?sulfur cells utilize. The sulfur cathode, being naturally abundant and environmentally friendly, makes lithium?sulfur batteries a potential next-generation energy-storage technology. The current state of the research indicates that lithium?sulfur cells are now at the point of transitioning from laboratory-scale devices to a more practical energy-storage application. Based on similar electrochemical conversion reactions, the low-cost sulfur cathode can be coupled with a wide range of metallic anodes, such as sodium, potassium, magnesium, calcium, and aluminum. These new ?metal?sulfur? systems exhibit great potential in either lowering the production cost or producing high energy density. Inspired by the rapid development of lithium?sulfur batteries and the prospect of metal?sulfur cells, here, over 450 research articles are summarized to analyze the research progress and explore the electrochemical characteristics, cell-assembly parameters, cell-testing conditions, and materials design. In addition to highlighting the current research progress, the possible future areas of research which are needed to bring conversion-type lithium?sulfur and other metal?sulfur batteries into the market are also discussed.

Dielectric properties of solid polymer electrolyte having PEO-PAM blend matrix with sodium trifluoromethane sulfonate (NaCF3SO3) as ionic salt have been studied. The samples have been prepared by solution cast technique. X-ray diffraction analysis has been carried to understand the formation of blend, complexation and crystallinity of the polymer blend with the variation of salt amount. Complex impedance spectroscopy has been used to study ionic conductivity, dielectric relaxation and modulus formalism as a function of frequency at various temperatures. Scaling of M? spectra has been carried out and it has been found that the dynamic relaxation processes occurring in the system are dependent on temperature as well as salt concentration. Highest conductivity at room temperature has been found to be 2.81.10-7 S/cm for sample with 17.5 wt% NaCF3SO3

The synthesis and characterization of the new ligand N,N-bis(2-quinolylmethyl)-N-bis(2-pyridyl)methylamine (2PyN2Q), a derivative of N,N-bis(2-pyridylmethyl)-N-bis(2-pyridyl)methylamine (N4Py) is reported. Purification of both N4Py and 2PyN2Q on Dowex cation exchange columns as their hydrochloride salts allowed the isolation of the byproducts N3Py and 2PyNQ, respectively. The X-ray crystal structure of [H2N4Py](PF6)2 shows that the two more basic picolyl nitrogens are protonated. X-ray structural analyses of the copper(II) complexes [Cu(N4Py)(NO3)](NO3) (1) and [Cu(2PyN2Q)(NO3)](NO3) (2) show that the binding of the nitrate ligand is influenced by the steric bulk of the quinoline rings while electrochemical studies show that the poorer basicity of the quinolinyl donors makes 2 more easily reduced than 1. X-ray structural analyses of the zinc(II) complexes [Zn(N4Py)(OH2)](CF3SO3)2·H2O (3a·H2O), [Zn(N4Py)(CH3OH)](ClO4)2·CH3OH (4·CH3OH) and [Zn(2PyN2Q)(NCCH3)](ClO4)2·CH3CN (6·CH3CN) again show that the quinoline rings have a significant influence on the way in which the monodentate ligand can bind to the zinc center. The X-ray crystal structure of [Zn(2PyNQ)2](ClO4)2 (7) is also reported. In 7 the zinc(II) ion is bonded to two pyridyl donors and one amine donor from each of two ligands and the quinolinyl donors are not bound.

A preparative procedure of potentially wide applicability is described for the synthesis of previously unreported tris(heteroleptic) [Cr(diimine)3]3+ complexes. The synthetic scheme involves the sequential addition of three different diimine ligands, and employs CrCl3 · 6H2O as the initial Cr(III) reagent. The synthesis and characterization of the complexes [Cr(TMP)(phen)(diimine?)]3+ are reported (where TMP = 3,4,7,8-tetramethyl-1,10-phenanthroline, phen = 1,10-phenanthroline; and diimine? is either bpy = 2,2?-bipyridine, Me2bpy = 4,4?-dimethyl-2,2?-bipyridine, 5-Clphen = 5-chloro-1,10-phenanthroline, or DPPZ = dipyridophenazine). Chiral capillary electrophoresis and electrospray mass spectrometry were essential aids in determining the presence or absence of diimine ligand scrambling. Utilizing emission and electrochemical data obtained on these compounds, the oxidizing power of the lowest lying excited state (2Eg(Oh)) was calculated, and was found to vary in a systematic fashion with diimine ligand type.

A series of complexes has been prepared of the form [Re(dien)(PPh3)(PF3)(L)]+ (dien = diethylenetriamine), where L is an unsaturated organic molecule. The range of ligands which form eta2-coordinate complexes with this metal center includes aldehydes, olefins, and dienes. In addition, thiophene, benzo[b]thiophene, and acetonitrile bind through their heteroatoms. Although {Re(dien)(PPh3)(PF3)}+ (dien = diethylenetriamine) displays chemical and spectroscopic characteristics of a potent pi-base, it fails to form stable eta2-coordinated complexes with aromatic molecules. However, its carbonyl analogue {Re(dien)(PPh3)(CO)}+, when combined with furan, forms the complex [Re(eta2-furan)(dien)(PPh3)(CO)][OTf], a rare example of a thermally stable eta2-heterocycle.

The syntheses and characterization of a series of chromium(III) complexes of the general types trans-[(A)4Cr(OH)-(H2O)]2+, trans-[(A)4Cr(OH)2]+, and trans-[(A)4Cr(H2O)2]3+ are described. The ligands (A)4 used include the tetradentate ligand 1,4,8,11-tetraazacyclotetradecane (cyclam), its hexamethylated derivative C-meso-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane (cyca), and the bidentate ligand 2-aminomethylpyridine (pico). The cobalt(III) aquahydroxo complexes with cyclam and cyca are also reported. The trans-diaqua and trans-dihydroxo complexes are monomeric, but the trans-aquahydroxo complexes form linear chains. The complexes trans-[Cr(cyclam)(OH)(H2O)](CF3SO3)2 1 and trans- [Co(cyclam)(OH)(H2O)](CF3SO3)2 3 and their corresponding perchlorates (2 and 4, respectively) have been isolated and the structures of the chromium triflate salt 1 and the cobalt perchlorate salt 4 have been determined. Both of these complexes 1 and 4 form infinite chains in the solid state, adjacent metal centers being bridged by hydrogen bonds between hydroxo and aqua ligands. The Cr … Cr separation in 1 is 6.085 A whereas the Co … Co separation in 4 is 6.078 A. The complex trans-[(pico)2Cr(OH2)2](NO3)3 ·H2O 8 (where pico is picolylamine, 2-aminomethylpyridine) crystallizes with only one monomeric formula in a unit cell. In contrast to the structures of 1 and 4 (and, presumably, of 2 and 3 also), the two complexes trans-[Cr(cyclam)(OH)2]-ClO4·H2O 5 and 8 are monomeric in the solid state. The chromium complex trans-[Cr(cyca)(OH)(H2O)](ClO4)2·H2 O 6 crystallizes with two monomeric formula units in a unit cell and the cobalt analogue 7 is isomorphous with the chromium complex. The structures of these complexes are also linear chains, but in this case there is an intervening water molecule between the aqua and hydroxo ligands on adjacent chromium centers. EPR spectroscopy of the chromium complex 1 doped in the diamagnetic cobalt host 3 reveals the presence of weak magnetic interactions.

A macrocyclic tetraamido ligand 5,6:(3-pyrido)-12,12-diethyl-2,2,9,9-tetramethyl-3,8,11,13-tetraoxo-1,4,7,10-tet raazacyclotridecane, H41, has been designed to incorporate CoII and CoIII in the primary coordination site and has a secondary bidentate site, comprising pyridine-N and amido-O donor atoms, that coordinates Lewis acids. The complex PPh4[2] was obtained by deprotonation of H41 with lithium diisopropylamide in the presence of CoCl2, followed by air oxidation and precipitation from water by addition of PPh4Cl. The X-ray crystal structure of PPh4[2] was obtained. The compound crystallizes in the space group P1 (No. 2) with unit cell dimensions a = 12.936(4) A , b = 13.253(5) A , c = 13.288(2) A , alpha = 93.75(2), beta = 90.91-(2), gamma = 91.53(3), V = 2272.1(1.2) A 3, and Z = 2. Lewis acids can be bound either reversibly as in the case of alkali and alkaline earth cations or irreversibly as found for [(bpy)2Ru]2+ (bpy is 2,2?-bipyridine) and [(Me2bpy)2Ru]2+ (Me2bpy is 4,4?-(CH3)2-2,2?-bipyridine). The Lewis acid in the secondary coordination site broadly modifies the chemistry at CoIII and CoII in [2]- and [2]2-, respectively. The axial binding affinity of the CoIII center for 1-CH3-imidazole was 1 to 2 orders of magnitude larger when divalent Lewis acids were in the secondary coordination site than that for [2]-. The reactivities of [2]2-, Ca2+/[2]2-, and [(bpy)2Ru[2]] toward O2 were significantly different. The reaction of [2]2- with O2 rapidly generated [2]-, apparently by an outer-sphere electron-transfer pathway. In contrast, the oxidation of Ca2+/[2]2- by O2 was a complex reaction in which some of the Ca2+ was consumed and the final species depended on the amount of Ca2+ present at the start of the reaction. Finally, in the case of [(bpy)2Ru[2]], it appeared as though the dinuclear complex [(bpy)2Ru[2]]2(mu-O2) formed upon reaction with O2.

This article describes two coordination polymers based on sodium and nickel triflates, respectively, and the linker adiponitrile (1,4-butanedinitrile). Sodium triflate forms a coordination network with adiponitrile, where the nitriles bridge the sodium ions, a rare coordination mode for a nitrile. Crystal structures of alkali metal complexes of linear aliphatic dinitriles have not been reported previously. With nickel triflate, a cationic 1-D coordination polymer results upon coordination of adiponitrile.

Self-assembly of ligand 1 and Pd(NO3)2 delivers Fujita-type metal-organic polyhedron (MOP) 3 which bears 24 covalently attached methyl viologen units on its external surface, as evidenced by 1H NMR, diffusion-ordered spectroscopy NMR, electrospray mass spectrometry, transmission electron microscopy, and atomic force microscopy measurements. MOP 3 undergoes noncovalent complexation with cucurbit[n]urils to yield MOPs 4-6 with diameter ?5-6 nm. MOP 5 can be fully loaded with doxorubicin (DOX) prodrug 2 via hetero-ternary complex formation to yield 7. The MOPs exhibit excellent stability toward neutral to slightly acidic pH in 10 mM sodium phosphate buffer, mitigating the concern of disassembly during circulation. The results of MTS assays show that MOP 7 is 10-fold more cytotoxic toward HeLa cells than equimolar quantities of DOX prodrug 2. The enhanced cytotoxicity can be traced to a combination of enhanced cellular uptake of 7 and DOX release as demonstrated by flow cytometry and confocal fluorescence microscopy. The confluence of properties imparted by the polycationic MOP architecture and plug-and-play CB[n] complexation provides a potent new platform for drug delivery application.
