Solar energy storage: A possible use of inclusion compounds

Solvent-Free Organic Synthesis

“…However, if the isomerization reaction is carried out in the channels of deoxycholic acid (332) by exposing the inclusion crystals to solar light, a significant decrease has been found in the amount of such byproducts. 122 The photoisomerization in the solid state of the alkyl group bonded to the cobalt atom in cobaloximes has been extensively studied. For example, the but-3-en-1-yl group in crystalline 333 is isomerized to the but-2-en-1-yl group of 334 in the solid state on exposure to a xenon lamp.…”

The monoclinic phase of the 2/1 inclusion compound between deoxycholic acid and o-xylene

“…Recently, the reaction processes studied were the isomerization of specific guests inside the cavities of DCA: the valence isomerization of norbornadienes (Guarino, Possagno & Bassanelli, 1987a), the cis/trans isomerization of stilbenes (Guarino, Possagno & Bassanelli, 1987b) and the position isomerization of xylenes (Guarino, Possagno & Bassanelli, 1988). In all these reaction processes the strict correlation between the isomerization yields and the photophysics of the host and of the guest moieties has been observed, as well as the influence of the symmetry of the sites where the reactions occur (Guarino, 1986(Guarino, , 1987.…”
