Catalysis was attributed to an enhanced reactivity of the iodide anion as a Lewis base when encapsulated within the polar environment of the quaternary ammonium dendrimer.

where rA, rB,and rXare the ionic radii of the A-cation, B-cation, and X-anion, respectively. Whentis larger than 1.0 or smaller than 0.71, a nonperovskite structure is favored. When the material has atof 0.9-1.0, an ideal cubic structure will form. In addition tot, the octahedral fac...
We next compare the structure and morphology of the perovskite films using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The PSG film has a preferential [001] orientation, while the control film has none as seen from the XRD patterns (Fig.4a, b). The preferential orientati...

The corrosion inhibition potentials of organic compounds depend on a number of factors such as the nature of the metal, the aggressive solution, molecular and electronic structure of the inhibitor, solubility and concentration of the inhibitor, pH and temperature. The molecular and electronic geometry...
Some studies have introduced semiconductor molecules containing Lewis acid or base functional groups to passivate trap states at grain boundaries and suppress over-crystallization [18,20,21,22,23]. Alkyl ammonium halide salts are also popular for the passivation of perovskite films, as they are ...
