摘要: Mg−Al layered double hydroxides (LDHs) intercalated with an anionic azobenzene derivative (AzAA) were prepared, and the arrangement of incorporated AzAA was investigated by varying starting AzAA/LDH ratios for two types LDHs different Mg/Al mole ratios, = 2.0 (LDH2) 3.0 (LDH3). The observed basal spacings complexes, 8 23−25 A, ascribed to horizontal (parallel layers) vertical (perpendicular orientations AzAA, respectively. In general, orientation low higher ratios. For LDH2 a large spacing 33 A intermediate that is, 0.5 0.75, which interpreted as alternate stacking interlayers (“1:1 ordered interstratification” or “second staging”). case LDH3 complexes having smaller layer-charge density, second staging not found wit...
