An amine is an uncharged organic compound that contains a functional group with the generic formula {eq}\rm NR_3 {/eq}. This functional group acts as a Bronsted-Lowry base to deprotonate water molecules. The conjugate acid product is positively charged, so it can be used as a cation in...
b,c) and photoluminescence (PL) spectra (d,e,f) of CH3NH3PbBr3NCs. Samples were synthesized at room temperature (RT) (a,d) and at 60 oC (b,e) with a varying amount of precursors and a fixed amount of ligands (5 μL oleylamine—OLA/50 μL oleic acid—OA).c,fshow the ...

and grain boundaries are thought to be responsible for causing recombination and trapping of charge carriers. Here we report an effective and reproducible way of treating grain boundaries in CH3NH3PbI3films deposited by means of a Lewis acid–base adduct approach. We show by high-resolution transmi...

The results indicate that the ratio between acid and base is very important for the cluster formation. The main interaction type changes from hydrogen bonding to a weak attraction as the number of bases increase. When the number of dimethylamine molecules is less than or equal to that of the ...

SPV can be used to study exponential defect states below the band gap of CH3NH3PbI3 and previous studies showed that the addition of a small amount of ammoniumvaleric acid iodide (AVAI) into solution containing CH3NH3I and PbCl2 leads to a reduction in the value of defects below the band...

The intracellular pH determined by used of the weak acid 5,5-dimethyl-oxazolidine-2,4-dione was significantly higher than that obtained with the weak base (CH 3) 2NH. By transmission electron microscopy it was shown that reticulocytes treated with NH 4Cl or CH 3NH 2 have enlarged ...
