Such layered double hydroxides can also serve as hosts for guests, such as carboxylates, sulfates, phosphates, porphyrins, and polyoxometallates that can be put in by anion exchange.85... [Pg.145]

Clays are colloidal layered hydrous aluminosilicates. There are relatively few examples of porphyrin intercalation into clays reported, mostly with either smectite clays or layered double hydroxides (LDH). Smectite clays consist of negatively charged layered aluminosilicate sheets. These sheets are separated by cations and water molecules. The... [Pg.94]

Photoinduced electron transport from EDTA to viologen through the excited Zn porphyrin and Ti02 particle entrapped within lithium aluminum-layered double hydroxide was attempted [387] (Fig. 19). Since the fluorescence of Zn porphyrin was quenched by TiO, the excited singlet state of porphyrin was supposed to transfer an electron to Xi02 particle. [Pg.266]

The intercalation of 5,10,15,20-tetra(4-sulfonatophenyl)porphine into the interlayer space of a layered double hydroxide has been accomplished by anion exchange (159). The powder X-ray diffraction pattern showed that the intercalated porphyrin anions are arranged with their molecular planes perpendicular to the host lamellae. [Pg.225]
