Abstract

UV/VIS absorption and emission spectroscopy is a powerful tool for probing solute-solvent interactions. Recently, we have identified the use of Nile Blue as a sensitive fluorescent probe in identifying the local nanoenvironment, such as confinement within clay nanolayers. In this study we examine the solvatochromic behavior of Nile Blue adsorbed montmorillonite in solvents of varying polarity and the influence of an adsorbed imidazolium surfactant. The fluorescence behavior in solvents is compared to its behavior in polymers with similar chemical structures to the solvents.
