Theoretical Studies of Photopumping in Photofacilitated Liquid Membranes and The [3+2] Cycloaddition of Carbonyl Oxides in the Synthesis of 1,2-Dioxolanes
We have conducted a series of simulations of doubly illuminated liquid membranes containing photoactive carriers in order to determine how well such membranes transport solute against a concentration gradient. In our model, the carrier can exist in either a strongly binding or weakly binding form, and both forms are photoactive. The interconversion between forms has an inherent rate constant in the dar, and the interconversion rate can be increased with light of an appropriate wavelength. We have explored systems in which the membrane is doubly illuminated so that both photoprocesses (strongly binging to weakly binding, and weakly binding to srongly binding) occur. We have found that doubly illuminated membranes should maintain higher mass transport rates against greater concentration gradients than will singly illuminated membranes. We have determined the range of membrane and carrier properties that result in the highest degree of photopumping under double illumination.
