Tunable Optical Properties and Self-Assemblies of a Water-Soluble Perimidinium Imide Dye.

This article discusses the synthesis and properties of a new type of dye called perimidinium imides. These dyes have tunable optical properties and can self-assemble in different solvents. The researchers synthesized two different perimidinium imides and studied their absorption and photoluminescence properties in various solvents. They found that the dyes exhibited different morphologies and optical properties depending on the solvent and concentration. The dyes also retained their emissive property in water, making them potentially useful for biological applications. [Extracted from the article]
