The equilibrium constant measurements provided absolute values for the intrinsic (gas-phase) acidities of the Brnsted acids CH3NH2, C2H5NH2, (CH3)2NH, and (CH3)3N, the heats of formation of their conjugate bases, and the electron affinities of the corresponding radicals R1R2N. Proton removal...
Classify each of the following as a Lewis acid or a Lewis base. Identify the Lewis acid and the Lewis base in the following reaction. B (OH)_3 (aq) + H_2 O (l) to B (OH)_4 (aq) + H^+ (aq) Identify the Lewis Acid and Lewis base in the following reaction: ...
By coating the film with an electron or hole transfer layer, [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) or 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD) respectively, we observed the charge transfer directly through the fluorescence ...
(Me3Sn)3N and CuX (X = halide).5In such latter cases of employing (Me3Sn)3N as the nitrogen transfer reagent, Lewis acid/base adducts of the general type [Ln(X)M·N(SnMe3)3] (M = metal, X = halide ligand, L = other ancillary ligands) ...

Moreover, Raman bands were sighted at about 788, 762, and 732cm1 for 2-propanol solutions of boric acid and attributed to B(OH)2(OCH(CH3)2), B(OH)(OCH(CH3)2)2, and B(OCH(CH3)2)3, respectively.doi:10.1016/j.vibspec.2012.02.002Shigeru Yamauchi...
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...
For the 3DP film deposition process illustrated in Figure 4b-top, the one-step solvent exchange process was used with the Lewis-base-acid adduct in 4:1 anhydrous DMF:DMSO with precursors MAI (1.5 M) and PbI2 (1.5 M), while the solution was stirred overnight at RT. Figure 4b-top ...
