Figure 1 | Schematic of micro-scale rigid frame engineering. Due to the weak spin-orbit coupling (SOC) and the molecular motion in the surrounding environment, as well as inhibitors like oxygen and water, triplet excitons are easily dissipated (Figure 1 left). Previously, researchers have employed various methods to protect triplet excitons, including multiple interactions such as hydrogen bonds and covalent bonds to limit molecular motion and reduce non-radiative transitions. Based on this, the authors' team proposed a rigid framework strategy to suppress the non-radiative transition from the excited triplet state to the ground state of CNDs through restricted interactions, thereby achieving efficient phosphorescent emission (Figure 1 right).
