The separation of photoproducts formed in photosensitized electron transfer reactions is essential for efficient energy conversion and storage. The organization of the components involved in the photo-induced process in interfacial systems leads to efficient compartmentalization of the products. Several Interfaclal systems, e.g., lipid bllayer membranes (vesicles), water-in-oil mlcroemulslons and a solid SIO2 colloidal Interface, have been designed to accomplish this goal. 

NB Used a Sirius PCAlOl autotitrator. Also gave log P (octanol-water) and log P (dioleylphosphatidylcholine unilamellar vesicles-water).

Effect of Polymers on Lamellar Dispersions. The effects of water-soluble polymers on lamellar dispersions are schematically summarized in Figure 7. Polymers are excluded from the vesicle water layers dq)ending on the preparation temperature and polymer molecular weight. This exclusion results in a polymer... 

Difference Spectroscopy. Spectral subtraction, or difference spectroscopy, is the final inqwrtant topic of this general description. In studies of "buik sanqiles such as micelles, bilayeis, or vesicles, water (or D2O), which is an intense absoiber throughout most of Ae mid-infrared spectrum (4000 400 cm ), is the solvent. The subtraction of the spectrum of liquid water from that of an aqueous solution of an analyte of interest can be accomplished routinely with many of the dedicated minicomputers used with modem FT-IR spectrometers. The spectrum of liquid water is recorded under the same conditions (cell padilengdi, tenqierature, cell window type) as the samples of interest, and digitally stor. Iliis reference spectrum of water can then be scaled by an appropriate midtiplfeative factor (usually near 1.0) and subtracted from the sample spectrum, to produce a spectrum of the...
