Fluorescent probe studies

From Chandar et al. (1987) based on the data of Somasundaran and Fuerstenau (1966). Chandar et al. (1987) have shown with the aid of fluorescent probe studies that in region II and above adsorption occurs through the formation of surfactant aggregates of limited size.

Reported examples of near-IR fluorescence probe studies in anisotropic media are harder to find at present, but no doubt this situation will change as the advantages of excitation in the near-IR, particularly with respect to reducing autofluorescence in biological systems, become more widely appreciated.

Interpolymer complexation between water-soluble polymers by hydrogen bonding was a frontier subject in the 1970s. Polyfcarboxylic acids), mainly po-lyfacryhc acid) (PAA) and poly( methacryflc acid) (PMAA), served as the most common proton-donating components. As for the proton-accepting polymers, poly(ethylene oxide ) (PEO or PEG) and poly(M-vinyl-2-pyrrolidone) (PVPo) were often used. The important results on the formation of complex aggregates and its dependence on the structur prameters have been reviewed [2,3,8]. In this section we select a few representative topics to look at recent advances in interpolymer complexes in aqueous media, with the emphasis on fluorescence probe studies.

Data from a fluorescence-probe study of the interaction of cyclohepta-amylose with arenes and amphiphilic molecules have been presented. The arene (pyrene) appears to interact with cyclohepta-amylose in an initial, fast inclusion process which is followed by a slower aggregation of the resulting complexes. Addition of surfactant molecules leads to complexing of the three components and thence to an increase in the hydrophobicity of the arene environment.
