In this study we developed a method for the pyridine-directed, rhodium-catalyzed, site-selective C–H alkylation and arylation of pyridones using commercially available trifluoroborate reagents. This simple versatile transformation proceeded smoothly under relatively mild conditions with perfect site selectivity. The coupling groups in boron reagents can be extended to primary alkyl, benzyl, cycloalkyl. Moreover, direct products could also obtained similar conditions.
Five 3D CPs were constructed from a designed π-conjugated aromatic pentacarboxylate with diverse structures.
Cu(II)-catalyzed C6-selective C–H thiolation of 2-pyridones with aryl and alkyl disulfides to provide functional thioethers has been achieved.
Polymer solar cells (PSCs) processed from non-halogenated solvents are favorable for large scale production. However, the photovoltaic performance of devices is generally inferior to that counterparts halogenated solvents. Herein, we report utilization 5-alkyl-4-(methylthio)thiophene (MTT) as a conjugated side chain polymeric donor achieve efficient PSCs toluene. The derived polymer PMTT56 exhibits lower energy levels than 5-alkyl-4-methoxythiophene (MOT) counterpart (PMOT39) and...
Rapidly quenched Pd82Si18 ribbon was prepared by melt spinning. The thermal stability and non-isothermal crystallization kinetics of amorphous were investigated differential scanning calorimeter measurements. Its structure X-ray diffraction transmission electronic microscopy. activation energy calculated the Kissinger method, nucleation growth during local Avrami exponent. average for based on method is 330.672 kJ/mol, indicating that it has high stability. glass determined...
Antireflection and superhydrophilicity performance are desirable for improving the properties of electronic devices. Here, we experimentally provide a strategy femtosecond laser preparation to create micro-nanostructures on graphite surface in an air environment. The modified is covered with abundant micro-nano structures, its average reflectance measured be 2.7% ultraviolet, visible near-infrared regions (250 2250 nm). wettability transformation from hydrophilicity realized. Besides,...
The Zhangquanzhuang gold deposit is a special in the Zhangjiakou district, on northern margin of North China Craton. It characterized by enrichment sulfides, scarcity tellurides and zero to positive sulfur isotope compositions compared with famous Dongping Xiaoyingpan Te-Au-Ag types same district. In this paper, we use in-situ LA-(MC)-ICP-MS bulk trace element concentrations pyrite, study physicochemical conditions mechanisms mineral deposition deposit. Pyrite from stage I (PyI) contains...
Organoboron compounds are important building blocks to create molecular diversity.Strategies that can transform the readily available hydrocarbons into these by C-H borylation highly attractive.In this context, significant progress has been made towards iridium-catalyzed borylation.Because substituted arenes typically contain ortho-, metaand para-C-H bonds, regiocontrol a long-standing challenge within type of chemistry.During past decade, in ortho-selective borylation, while...
Sanan oilfield has entered late stage of high water cut development. It urgently needs accurate prediction remaining oil distribution. But previous studies on 3D structure were far could not meet the requirements fine reservoir description. This paper applied RMS, a piece excellent geological modeling software establishing structural model typical block in bases seismic interpretation data. included 28 faults’ model, 11 horizons’ and model. And then measured analyzed faults elements Based...
The InnoSlab laser has the advantages of excellent thermal management and high overlapping efficiency. In this work, we report an with efficiency at 1319 nm end-pumped 0.6at.% Nd:YAG by 808 nm. hybrid stable–unstable resonator was adopted. For a cavity length 17.9 mm absorbed pumped power 423.5 W, output 81 W obtained T = 5%, exhibiting optical conversion 19.13% slope 29.80%.
