The field-effect transistor method is used to study the mobility of charge carriers in layers lead sulfide nanocrystals with ligands tetrabutylammonium iodide and 1,2-ethanedithiol create solar cells. difference between operating a ambient air an inert atmosphere demonstrated. It shown that, air, processes charging are activated when current flows, influence polarization interface insulator on ...

Near-IR semiconductor colloidal nanoplatelets (NPs) are a new and promising class of materials for the development photodetectors because they can effectively absorb visible infrared optical radiation. In this work, we study photoconductivity HgTe with ligands 1,2-ethanedithiol tetrabutylammonium iodide. It has been shown that choice is key factor in achieving high operational characteristics. ...

Tetrabenazine (TBZ), a high affinity and specific inhibitor of the vesicular monoamine transporter, has been labeled with carbon-l 1 as a potential probe for in viva positron emission tomographic imaging of monoaminergic neuronal losses in neurodegenerative diseases. [“CITBZ was synthesized by O-[“Clmethylation of the 9-0-desmethylTBZ using [“C]methyl iodide in the presence of tetrabutylammoniu...

This work reported the successive incorporation of tetrabutylammonium (TBA) into Methylammonium lead Iodide (MAPbI 3 ) perovskite. The thin films were characterized by X-Ray diffraction (XRD), Scanning electron microscopy (SEM), Transmittance (TEM), Atomic force (AFM), and UV-Visible spectroscopy. It was shown that introducing TBA increases crystallinity, grain size, surface morphology without ...

2-Amino-3-acylthiophenes are known to allosterically modulate the A(1) adenosine receptor and are also used as intermediates in the synthesis of therapeutic agents and pharmacophores such as thienoazepines and thienopyrimidines. The N-alkylation of 2-aminothiophenes has been notoriously difficult to accomplish under mild conditions and there are very few examples of N-alkylated 2-aminothiophene...

Vibration ball-milling in a zirconia-lined vessel afforded clean and quantitative nucleophilic displacement reactions between 4-methoxybenzylthiolate salts and nucleoside 5'-halides or 5'-tosylates in five to 60 minutes. Under these conditions, commonly-encountered nucleoside cyclisation byproducts (especially of purine nucleosides) were not observed. Liquid-assisted grinding of the same 5'-iod...

 A simple, mild and practical procedure has been developed for the synthesis of symmetrical and unsymmetrical ethers by using DMSO, TBAI in the presence of K2CO3. We extended the utility of  Potassium carbonate as an efficient base for the preparation of ethers. A wide range of alkyl aryl and dialkyl ethers are synthesized from treatment of aliphatic alcohols and phenols with various alkyl hali...
