Abstract

The aggregation of a surfactant squaraine, 4-(N-methyl-N-(carboxypropyl) amino) phenyl-4'- (N, N-dibutylamino)-phenylsquaraine (SBA), has been studied in a variety of media, including organic solvents, aqueous cyclodextrin (CD) solutions, vesicles, monolayers, Langmuir-Blodgett films, and pure solid dye films. As a monomer in organic solvent, SBAexhibits sharp and intense absorption with A,, ranging from 622 to 656 nm and ...
