Abstract

A novel surfactant-like non-ionic fluorophore, 3-(bis (2-hydroxyethyl) amino)-N-(4-(pyrene-1- sulfonamido) butyl) propanamide (PSDA-DEA), was designed and prepared. Fluorescence and surface tension studies revealed that the fluorophore aggregates in aqueous medium, and its critical aggregation concentration (CAC) is∼ 3.3× 10− 5M. Cryogenic transmission electron microscopy (cryo-TEM), dynamic light scattering (DLS) and atomic force ...
