Atomic layer deposition (ALD) was used to fabricate magnesium phosphate thin films as a magnesium-ion conducting solid electrolyte. The deposition was carried out at lower deposition temperatures, ranging from 125 to 300 C. The film exhibits an amorphous nature and excellent step coverage, even in narrow trenches with a higher aspect ratio. The growth rate and the ionic conductivity were found to increase with a decrease of the deposition temperature. This can be explained by increased disordering of the phosphate matrix, giving rise to enhanced hopping conduction of magnesium ions. The film deposited at 125 C showed an ionic conductivity of 1.6 × 10-7 S cm-1 at an ambient temperature of 500 C, with an activation energy of 1.37 eV. These values are better than those of the film deposited at 250 C as well as of a sputtered film. Our results indicate that ALD has great potential for the fabrication of magnesium-based solid electrolyte films.

We report here a ?nonspectator? behavior for an unsupported L-function sigma3-P ligand (i.e. P{N[o-NMe-C6H4]2}, 1a) in complex with the cyclopentadienyliron dicarbonyl cation (Fp+). Treatment of 1a?Fp+ with [(Me2N)3S][Me3SiF2] results in fluoride addition to the P-center, giving the isolable crystalline fluorometallophosphorane 1aF?Fp that allows a crystallographic assessment of the variance in the Fe?P bond as a function of P-coordination number. The nonspectator reactivity of 1a?Fp+ is rationalized on the basis of electronic structure arguments and by comparison to trigonal analogue (Me2N)3P?Fp+ (i.e. 1b?Fp+), which is inert to fluoride addition. These observations establish a nonspectator L/X-switching in (sigma3-P)?M complexes by reversible access to higher-coordinate phosphorus ligand fragments.

Developing stable and cheap organic cathode interlayers (OCIs; to replace metal cathode and expensive OCIs for enhancing the device stability and reducing the manufacturing cost) is an important topic for commercial applications of polymer solar cells (PSCs). Herein, four one-step synthesized organic electron transport layers (G-Series electron-transport layers [ETLs]) with a novel star-shaped molecular structure consisting of a series of different heteroatom atoms as cores and sulfobetaine ions as a terminal substituent are explored. The energy levels can be finely tuned by applying different heteroatom atoms as cores. With the conventional device structure with poly[[2,6?-4,8-di(5-ethylhexylthienyl)benzo[1,2-b;3,3-b]dithiophene][3-fluoro-2[(2-ethylhexyl) carbonyl]thieno[3,4-b]thiophenediyl]] (PTB7-Th) as a donor and [6,6]-phenyl-C71-butyric-acid-methyl-ester (PC70BM) as an acceptor, the G-C2-based devices exhibit a power conversion efficiency (PCE) of 8.90% with Al as the top electrode, much higher than that of the corresponding Ca/Al-based device (7.43%). Furthermore, G-Series-based solar cells are also more stable than the reference device based on Ca. In addition, these easy-to-get ETLs can be widely suitable for other PSCs based on different active layer systems. This work not only shows a new strategy for fine-tuning energy levels of nonconjugated zwitterionic molecules but also provides simple and stable ETLs for low-cost and high-performance PSCs.

A series of compounds with the general formular R3PE*AlCl3 (R = Ph or NMe2, E = S or Se) has been examined by n.m.r. spectroscopy as a contribution toward the characterisation of the P-E bond and the co-ordinate bond.Two derivatives, Ph3PS*AlCl3 and Ph3PSe*AlCl3, have been studied by X-ray crystallography. , a = 8.967(2), b = 12.626(4), c = 18.242(4) Angstroem,alpha = 84.83(2), beta = 89.02(2), gamma = 85.67(2) deg, Z = 4, R = 0.044.> In contrast to the oxygen analogues, the sulphur and selenium derivatives exhibit bent geometries .The structures are maintained in solution, as demonstrated by the 27Al n.m.r. spectra.The 31P and 13C n.m.r. spectra are informative of the changes associated with adduct formation, and show the oxygen derivatives (E = O) to be unique.Disruption of the P-E ? interaction due to adduct formation is more dramatic for the sulphur and selenium than for the oxygen derivatives.The extensive information available in the literature is re-evaluated in the light of the present results, and a classification for the co-ordinative bonding modes of the phosphine chalcogenides is proposed.

Reaction of amide bonds in t-butyldimethylsilyl-protected inosine, 2?-deoxyinosine, guanosine, 2?-deoxyguanosine, and 2-phenylinosine with commercially available peptide-coupling agents (benzotriazol-1H-yloxy)tris(dimethylaminophosphonium) hexafluorophosphate (BOP), (6-chloro-benzotriazol-1H-yloxy)trispyrrolidinophosphonium hexafluorophosphate (PyClocK), and (7-azabenzotriazol-1H-yloxy)trispyrrolidinophosphonium hexafluorophospate (PyAOP) gave the corresponding O6-(benzotriazol-1-yl) nucleoside analogues containing a C-O-N bond. Upon exposure to bis(pinacolato)diboron and base, the O6-(benzotriazol-1-yl) and O6-(6-chlorobenzotriazol-1-yl) purine nucleoside derivatives obtained from BOP and PyClocK, respectively, underwent N-O bond reduction and C-N bond formation, leading to the corresponding C6 benzotriazolyl purine nucleoside analogues. In contrast, the 7-azabenzotriazolyloxy purine nucleoside derivatives did not undergo efficient deoxygenation, but gave unsymmetrical nucleoside dimers instead. This is consistent with a prior report on the slow reduction of 1-hydroxy-1H-4-aza and 1-hydroxy-1H-7-azabenzotriazoles. Because of the limited number of commercial benzotriazole-based peptide coupling agents, and to show the applicability of the method when such coupling agents are unavailable, 1-hydroxy-1H-5,6-dichlorobenzotriazole was synthesized. Using this compound, silyl-protected inosine and 2?-deoxyinosine were converted to the O6-(5,6-dichlorobenzotriazol-1-yl) derivatives via in situ amide activation with PyBroP. The O6-(5,6-dichlorobenzotriazol-1-yl) purine nucleosides so obtained also underwent smooth reduction to afford the corresponding C6 5,6-dichlorobenzotriazolyl purine nucleoside derivatives. A total of 13 examples were studied with successful reactions occurring in 11 cases (the azabenzotriazole derivatives, mentioned above, being the only unreactive entities). To understand whether these reactions are intra or intermolecular processes, a crossover experiment was conducted. The results of this experiment as well as those from reactions conducted in the absence of bis(pinacolato)diboron and in the presence of water indicate that detachment of the benzotriazoloxy group from the nucleoside likely occurs, followed by reduction, and reattachment of the ensuing benzotriazole, leading to products.
