This acidic cation can be paired with a spectator anion that is a conjugate base of a strong acid. Dissolving such a compound in pure water creates an acidic aqueous solution. The compound first dissociates into its constituent ions, followed by the acidic cation forming a dissociation ...
The greatest challenge for halide perovskite QDs is the poor stability in the environment of air, moisture, acid, base and light illumination. Herein, we introduce a brief, feasible and efficient method to improve the stability of MAPbBr3 QDs through encapsulating them in ZrO2 sol framework. ...

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 ...

The 1H NMR spectra, with 11B noise decoupling, of B(C2H3)3 and its Lewis acid base adducts with NH3, N(CH3)3 and P(CH3)3 are reported. The broadening of the vinyl regions of the coupled spectra arises predominantly as the result of isotropic J(11B 1H) coupling and is not a ...
