Chemists Create The Brightest Fluorescent Material Ever
If you are interested in the neon color craze from lighting to body paints, this news is for you because, with the formula developed by chemists, fluorescent lights have become even more dazzling. This study, published in the journal Chem, included statements that new material was used for the dyes and that it captured the brightest fluorescent light known.
Previously, the problem with fluorescent dyes was; When the dyes were transformed into solid optical materials, homogeneous-complete mixing could not be achieved, so it could not fully show itself in terms of brightness. When the dyes become solid, they are subjected to a process called “quenching” because they are crushed and the fluorescence intensity decreases accordingly.
To overcome this inability to shine, the researchers followed a path: They prepared a clear solution with a star-shaped molecule called a cyan star. They treated a colored dye with this solution at the stage of turning it into a solid. This molecule, called cyanoctar, has a lattice-like structure and has managed to keep the dyes away from each other.
The name of this new class is SMILES
AmarFlood, a chemist at Indiana University and a senior member of the research team; “The fact that the dyes were too close to each other was a problem in terms of the quenching process and the connection between the dyes. Just as young children can’t help getting mixed up in storytimes, just like when they’re not acting like an individual, they can’t do without touching each other, ”he says.
As the paint became solid with the clear cyan star solution, small molecular ionic isolation lattices were formed. This structure is in a brand new material class. Small molecule ionic isolation cages or SMILES (you read it wrong, SIMILES) became the name of this new class. Previous studies have attempted to use macro rings to divide the dyes to keep the paint particles away, but these rings had their colors and the paint colors were printed. What Flood realized was that these macro rings had to be colorless for the fluorescence to fully reveal its radiant potential.
“Some people think colorless macro rings might not be effective enough, but as you can see, these isolation lattices do not suppress the colors of the dyes like macro rings and allow the fluorescence to show its full brightness. The application potential of this material exists for any technology that requires bright fluorescent light, including solar panels, bio-imaging, and lasers,” says Flood.
“This material is completely new, so we don’t know the boundaries of the material, what kind of properties it has, and how they are functional. We will build on a new foundation of understanding and try to understand how it works. Let’s see what more features it has and what kind of strict rules do these new features have ”
