The solid polymer electrolyte films consisting of polyacrylonitrile (PAN) as the host polymer, lithium triflate (LiCF3SO3) and sodium triflate (NaCF3SO3) as dopant salts were prepared by the solution cast technique. The pure PAN film was prepared as a reference. The films were characterized using a.c. impedance spectroscopy. At room temperature, the highest conductivity for the sample from the (PAN+LiCF3SO3) system and the (PAN+NaCF3SO3) system is 3.04 × 10-4 Scm-1 and 7.13 × 10-4 Scm-1, respectively. The temperature dependence of ionic conductivity for the highest conducting film from both systems follows the Arrhenius equation in the temperature range of 303 K to 353 K. The frequency dependence of ionic conductivity, rho, complex permittivity, epsilon?, and complex electrical modulus, M?were studied at different temperatures. The ionic conductivity and the dielectric behavior are described in terms of ion diffusion and polarization.

This paper describes the iron and ruthenium complexes ligated by 2,6-di(5-pivalamido-1H-pyrazol-3-yl)pyridine (amide-LH2) bearing electron-withdrawing NHCOBut groups on the two protic pyrazole arms. Treatment of FeCl2·4H2O with an equimolar amount of amide-LH2 followed by addition of two trimethylphosphine and an excess of sodium triflate gave the pincer-type iron complex [Fe(MeCN)(amide-LH2)(PMe3)2](OTf)2 (1b; OTf = OSO2CF3). Impact of the amido groups in 1b on the reactions with hydrazines was evaluated. Complex 1b catalyzed disproportionation of hydrazine into ammonia and dinitrogen, although the catalytic activity was lower than that of the But-LH2 analogue 1a. X-ray analysis of 1b as well as the ruthenium complex [{RuCl2(PPh3)2}2(mu2-amide-LH2)2] (2b) revealed that the pendant carboxamide groups along with the pyrazole NH units are engaged in hydrogen bonds in the second coordination sphere.

A new one-dimensional double chain photoluminescent Hg(II) coordination polymer (CP), {[Hg(L)2]·(ClO4)2}n (1), was synthesized using a benzimidazole-appended tripodal tridentate ligand, 1,3,5-tris(benzimidazolylmethyl)benzene (L). The dynamic and flexible framework of 1 allows it to be entitled as first Hg(II)-based CP belonging to the rare category of CPs that exhibit multistimuli-responsive photoluminescence sensing properties and called as “smart” material. The sensitivity of this material via luminescence quenching method showing “turn off” behavior to a range of stimuli, including anions, solvents, and nitroaromatic compounds (NACs), offers more fine-grained control over its properties. 1 can easily adjust its channel dimensions to encapsulate different guest anions forming complete/partial anion-exchanged materials 1A-1B/1C-1E using NO3-, BF4-, OTf-, OTs-, and PF6- anions, respectively. Reversible (1A and 1B) and irreversible (1C-1E) anion exchange behaviors were observed for the complete and partial anion-exchanged products, respectively. The noteworthy feature of the anion-exchanged compounds is their anion-triggered luminescent behavior depending on different properties of anions.The excellent emission in water and high hydrolytic stability of 1 allows its use for rapid and efficient fluorescence-based detections of NACs in aquatic system. The uncoordinated pendant benzimidazole moiety in 1 serves as Lewis basic recognition site for trinitrophenol (TNP) detection, and along with electron- and energy-transfer mechanisms, 1 forms a luminescent probe for detection of TNP with low detection limits (0.55 ppm), exhibiting excellent photostability and recyclability. 1 also represents the first reported Hg(II)-based sensory CP material that can discriminate nitrophenol and nitroaniline isomers through fluorescence sensing.

Five novel cationic cyclometalated Ir(III) complexes of type [(C?C)IrX(PPh3)2(dmbpy)]A (X = halogen; dmbpy = 4,4?-dimethoxy-2,2?-bipyridine; A = counterion) were synthesised and characterised. Complexes 1?3 ([(C?C)IrCl(PPh3)2(dmbpy)]A) have different anions (A = Cl?, CF3SO3 ?, PF6 ?) and complexes 4?5 ([(C?C)IrX(PPh3)2(dmbpy)]PF6) have different halogen ligands (X = Br?, I?). Changing either the counter anion or halogen ligand altered the photophysical properties of the complexes. Interestingly, complex 1 (X = Cl, A = Cl?) did not exhibit mechanochromism, while the other four complexes all displayed mechanochromic properties. Crystal structures were determined for all compounds, and two types of single crystals are obtained for compounds 4 and 5. All complexes displayed bright solid-state phosphorescence, and reversible room-temperature mechanochromic luminescence was observed for complexes 2?5. The mechanism of the mechanochromic behaviour was investigated by combining powder and single-crystal X-ray diffraction analyses.

A unique coupled redox organocatalysis system using flavin and iodine catalysts efficiently promoted the metal-free aerobic oxidative direct sulfenylation of indoles with thiols at ambient temperature without any sacrificial reagents, except environmentally benign molecular oxygen. Biomimetic flavin catalysis plays multiple roles in aerobic oxidative transformations, not only regenerating I2 from in situ generated I-, but also converting thiols into disulfides.

We report the syntheses, characterization, electronic structures and magnetic properties of four redox pairs of novel nickel-extended metal-atom chain (EMAC) complexes containing pyridine-, naphthyridine- and sulfonyl-containing ligands (H2Tspnda and H2Mspnda) (1-2 and 5-6). We further study the corresponding phenyl-substituted ligands (H2Tsphpnda and H2Msphpnda) (3-4 and 7-8) to examine the details of ligand effects. The X-ray structure of one-electron-reduced [Ni5]9+ complexes shows shorter Ni-Ni bond distances (2.2646(6) for 1, 2.2943(7) for 3, 2.2436(11) for 5 and 2.2322(8) A for 7) in comparison with an average Ni-Ni distance of 2.3187(8) A for these complexes, indicative of a partial metal-metal bond interaction in the mixed-valence [Ni2]3+ (S = 3/2) unit. The most striking result is that the [Ni2]3+ site migrates from Ni(1)-Ni(2) to Ni(2)-Ni(3) when we replace the p-tolyl-sulfonyl group with methyl-sulfonyl group. These complexes present a rare example of the effect of crystal packing on the symmetric molecular structure yielding unsymmetric electronic distribution. Cyclic voltammetry measurements show four reversible redox waves and display the lower potentials of the [Ni5]9+ complexes. These unusual lower potentials facilitate one-electron oxidation of these four complexes to [Ni5]10+-core forms. We applied the magnetic susceptibility and EPR measurements to examine the magnetic properties of these four [Ni5]9+-core pentanickel complexes and study the bonding nature of these mixed-valence [Ni2]3+ units. Indeed, the results of EPR measurements reflect the migration of the mixed-valence site and the change of symmetry. Surprisingly, the oxidized [Ni5]10+ counterparts behave differently: complex 2 exhibits an antiferromagnetic interaction with J = -13.59 cm-1 between the two terminal Ni ions, while the others (4, 6 and 8) display diamagnetic properties as all of the Ni2+ ions are in low-spin (S = 0) states. These three complexes, to the best of our knowledge, are the first examples of all Ni2+ ions in a null spin configuration for pentanickel chains. Even though the structures of these complexes are similar to each other, their corresponding electronic structure and oxidized products show drastic changes in their magnetic properties and bonding nature. These differences of the properties and bonding nature of these pentanickel complexes are attributed to the ligand effects.

Tertiary cyclopropanols easily available from carboxylic esters have been used in the synthesis of distally fluorinated ketones. Cyclopropane ring cleavage reactions in methanol with aqueous tert-butyl hydroperoxide in the presence of a copper(ii) acetate catalyst and sodium triflinate (Langlois reagent) afford beta-trifluoromethyl ketones in 16-74% isolated yields. Sodium triflinate serves as a precursor of reactive trifluoromethyl copper species, enabling ring-opening trifluoromethylation, as evidenced by mechanistic studies. We also demonstrate here that other sulfinate salts, such as sodium 1,1-difluoroethanesulfinate, sodium 2-(4-bromophenyl)-1,1-difluoroethanesulfinate and sodium 1-(trifluoromethyl)cyclopropanesulfinate, can be used as fluoroalkylation reagents, resulting in the corresponding fluorinated ketones.

The reactions of [Fe2(OH)(R3CCOO)2(Me3tacn)2]+ (R = F (1-F), Me (1-Me), Ph (1-Ph)) with dioxygen initially afford a mu-oxo bridged mixed valent diiron(II)(III) complex [Fe2O(R3CCOO)2(Me3tacn)2]+ (R = Me (2- Me) and Ph (2-Ph)) and subsequently the diiron(III) complexes 3-Me and 3-Ph. The reactions in acetonitrile are fast for 1-F, slower for 1-Me, and slow enough for 1-Ph so that crystals of 2-Ph as the triflate (2-Ph-OTf) and BPh4 salts could be isolated and their structures determined. The oxidant N- methylmorpholine N-oxide (MMNO), is cleaner in that the byproduct, H2O, does not further oxidize 2 as does the byproduct, H2O2, from the reaction with O2. The crystal structures indicate that 2 has an oxo bridge with the Fe···Fe distances in 2-Ph-OTf (3.123(1) A) and 2-Ph-BPh4 (3.155(1) A) similar to those of 3. The magnetic susceptibility data are fit for 1-Ph to two equivalent high-spin Fe(II) sites with H = 2JS1·S2, D = 2.823, g = 2.00, and J = -12.1 cm-1, for 2-Ph to an S = 1/2 ground state with a high- spin Fe(III) site with D = 1.46, g = 2.00, and a high-spin Fe(II) site with D = 13.93, E/D = 0.285, g = 2.069, and J = -144 cm-1, and for 2 Me to an S = 1/2 ground state with a high-spin Fe(III) site with D = 2.39, g = 2.00, and a high-spin Fe(II) site with D = -11.42, g = 2.041 and J = -119 cm-1. The EPR spectrum is consistent with the S = 1/2 ground state (g = 1.97, 1.93, 1.90 at 10 K) and is observed even at 85 K. The Mossbauer of 2-Ph exhibits a poorly resolved doublet suggesting a Class II mixed valent species (Fe(II) and Fe(III) sites with delta = 1.09, 0.6, DeltaE(Q) = 2.45, 2.35, and Gamma = 0.55, 0.75 mm s-1, respectively). Electrospray mass spectra in MeCN with 18O labeled 1- -Ph and 1-Me indicated that they reacted by an outer-sphere process with 16O2 or MMN16O as none of the oxidant is incorporated into 2.
