A joint effort between researchers at Indiana University and the University of Copenhagen has yielded a new class of materials, called small-molecule ionic isolation lattices (SMILES), which the researchers say are the brightest fluorescent materials in existence.
To create this material, the researchers mixed a colored dye with a colorless solution of cyanostar, a star-shaped macrocycle molecule that prevents the fluorescent molecules from interacting as the mixture solidified, keeping their optical properties intact. As the mixture became a solid, SMILES formed, which the researchers then grew into crystals, precipitated into dry powders, and then finally spun into a thin film or incorporated directly into polymers.
