A team of scientists at the Department of Inorganic and Physical Chemistry (IPC), the Indian Institute of Science (IISC), designed a new chiral aminoborane molecule that shows the persistent phosphorescence of room temperature and a circular polarized luminescence (CPL).
IISC said it offers a promising route for new generation photonical materials that are without metals, lightweight and structurally tuned.
More applications
“However, phosphoresoreal materials that shine after light exposure, decisive for safety and sensing applications are from ink.
He added that long -term phosphorescence remains exceptionally rare among organic materials.
“In addition, CPL integration – useful for advanced display and encryption technologies – with phosphorescence in small organic molecules remained largely elusive,” he added.
In a study published in Communication Chemistry, the team presented the potential of these new molecules in anti-poverty. They formulated inks using phosphoresoreal molecules and showed how hidden information can be detected selectively.
Visibility
“For example, under UV light, a show message appears as 1180 from its fluorescent response. But when the light source goes out, the IISC text appears in the dark, with the persistent resistance mold.
Looking into the future, the team focuses on improving the system’s emission efficiency, which could increase its usefulness in bioimaging and photonic materials. “With precise molecular design, we are beginning to bridge the gap between structural rigidity and multifunctional emissions. This work adds a new chapter to the ongoing story of small organic phosphors,” said P. Thilagar, professor in IPC and corresponding author.
