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.

Draw the Lewis dot structures, including brackets and their charge, for each of the following. a. Bromide ion b. Zinc ion c. Barium ion Sketch the following molecule: CH3NH2 (skeletal structure H3CNH2). Include all hydrogen atoms and nonbonding ele...
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...
