Room-Temperature Phosphorescent Host–Guest System Enables Dynamic Organic Radical Complex Emission
By
Yuping Dong
Summary
This article discusses the development of a room-temperature phosphorescent host–guest system that enables dynamic emission from organic radical complexes. It covers the challenges of stabilizing organic radicals (which are highly reactive due to unpaired electrons) and presents a strategy using a host–guest approach to achieve controlled phosphorescent emission at room temperature. The research addresses fundamental limitations in organic radical chemistry and opens new possibilities for applications in optoelectronics and spintronics.

· 3 pulledOrganic radicals with unpaired electrons play a pivotal role in organic chemistry, spintronics, and magnetics.
Radicals are generally highly reactive, making them difficult to control and prone to quenching.
Various stabilization strategies have been explored, such as introducing steric hindrance and delocalizing unpaired electrons.
