For color-pure phosphorescence organic light emitting diodes (PHOLEDs), we synthesized the trifluoromethyl sulfonyl substituted ligand and two new blue Iridium complexes with perfluoro-sulfonyl group (SOCF3pic and SOCF3mpic). The both iridium complexes showed similar photophys. and thermal properties while the HOMO energy leves of two Iridium complexes slightly differnet to be -5.84 eV for SOCF3pic and -5.74 eV for SOCF3mpic, resp. The device with the SOCF3mpic dopant exhibited higher device efficiencies of 7.17 cd/A and 3.7% compared to that with the SOCF3pic dopant (4.03 cd/A and 2.78%). Two-dimensional GIXD images of scattered X-ray intensity from surface to full depth for SOCF3pic-doped and SOCF3mpic-doped TCTA:4PTPS films were characterized for preferential orientation along the out-of-plane direction.

Patnaik, Sai Gourang; Jayakumar, Tejkiran Pindi; Sawamura, Yukihiro; Matsumi, Noriyoshi published the artcile< Defined Poly(borosiloxane) as an Artificial Solid Electrolyte Interphase Layer for Thin-Film Silicon Anodes>, Computed Properties of 576-83-0, the main research area is LIB defined polyborosiloxane artificial SEI silicon anode.

Solid electrolyte interphase (SEI) formation in Li-ion batteries is essential for good long-term performance of the cell. However, for electrodes exhibiting high volume expansion (like Si and Sn), continuous SEI formation can not only deplete electrolyte content but also increase cell impedance and hence mediocre performance. This is particularly detrimental in the case of thin-film electrodes where there is a minute amount of active materials loading. In the current work, defined poly(borosiloxane) (PBS) as an artificial polymeric SEI having self-healing, anion-trapping properties, and electron-deficient boron moiety is investigated. Studies on thin-film Si electrodes show excellent enhancement with polymeric coating in terms of cycling stability. These improvements are attributed to a combination of factors including the anion-trapping effect of tricoordinate boron, self-healing ability of PBS, and adherence to the electrode surface.

Series of novel sulfone derivatives containing 1,3,4-oxadiazole moiety I [R1 = 4-F-2-Me, 2,5-Cl2, 2-Br-4-F, etc.; R2 = Me, Et, CH(CH3)2, n-propyl] and II [R2 = Me, Et, CH2Ph] were synthesized. All the target compounds were characterized by 1H and 13C NMR, IR spectroscopy and elemental anal. Their antifungal activities were tested in vitro with six important phytopathogenic fungi, namely, Gibberella zeae, Fusarium oxysporum, Cytospora mandshurica, Phytophthora infestans, Paralepetopsis sasakii and Sclerotinia sclerotiorum using the mycelium growth inhibition method. Their antibacterial activities were tested in vitro with two important phytopathogenic bacteria, namely, Xanthomonas oryzae and Ralstonia solanacearum from tobacco bacterial by the turbid meter test. Compounds I [R1 = 2-Cl-4-F, 4-CF3; R2 = Me] and II [R2 = Me, Et] exhibited the most potent inhibition against R. solanacearum and X. oryzae with 50% inhibition concentration (EC50) from 1.97 to 7.75 μg/mL and 0.45 to 0.52 μg/mL, resp. Their antifungal tests indicated that among target compounds exhibited good antifungal activities against six kinds of fungi, especially against S. sclerotiorum with EC50 from 3.71 to 17.44 μg/mL. In vivo antibacterial activities tests demonstrated that the controlling effect of compound II [R2 = Me] (81.9%) against rice bacterial leaf blight were better than that of bismerthiazol (50.8%) and thiodiazole-copper (44.7%). The results also demonstrated that compounds I [R1 = 2-Cl-4-F; R2 = Me] and II [R2 = Me, Et] had a better antifungal and antibacterial activity, with good characteristics of broad spectrum. The structure-activity relationships were also discussed.

Transition-metal-catalyzed dehydrogenative C-H allylation with 1,1-disubstituted alkenes via β-H elimination remains challenging, because of the low reactivity and difficulty of controlling selectivity. Herein, the development of a Pd(II)-catalyzed directed atroposelective C-H allylation with methacrylates is described. Exclusive allylic selectivity was achieved. A vast array of axially chiral biaryl-2-amines are efficiently synthesized with excellent enantioselectivities (up to >99% enantiomeric excess).

A Cu-BTC (MOF-199) [copper(II)-benzene-1,3,5-tricarboxylate] catalyst has been synthesized and evaluated for imine synthesis from amine compounds under neat conditions. The performance of the Cu-BTC MOF was significantly higher than that of the CuO supported on Al2O3, TiO2 and SiO2 catalysts. The role of surface Lewis acid sites on the catalyst in the formation of imine products was illustrated by the pyridine-IR studies. The recovered Cu-BTC catalyst demonstrated consistent activity for five cycles under similar exptl. conditions. The physicochem. properties of the catalysts were analyzed by XRD, BET-SA, FT-IR, UV-DRS, SEM, TEM, XPS and pyridine adsorbed DRIFT spectroscopy.

Ariano, R. published the artcile< Determining the proportion of cement in finished concrete>, Synthetic Route of 82-73-5, the main research area is .

The methods of Kriege (cf. C. A. 25, 4680) and Florentin (cf. C. A. 21, 3440) consist in solubilizing the SiO2 of the cement (which is present as Ca silicates) by treating with HCl and then determining it by the usual methods. In Scheibe’s method (cf. C. A. 29, 8273.5) the coarse aggregate is eliminated, the residue (sand and cement) is pulverized and the portions soluble and insoluble in HCl are determined after calcination; it is assumed arbitrarily that the sum of the loss on ignition and the insoluble matter in the cement = 3%. It is then easy to calculate the amount of cement. None of these methods gives reliable results, and the same is true of indirect methods based only on the finished concrete and on samples of the sand and gravel entering into its composition There always remains a certain degree of uncertainty if the complete composition of the cement and the loss on ignition are not known. It should be noted that in all cases where the concrete itself is analyzed, the results give the composition of the finished concrete, and not that of the original mix. For the water also, it is possible to establish only the quantity which is actually combined in the concrete.
