Self-supplying coreactant radical and structural distortion induced by carbonate ligand in metal–organic framework for anomalous deep-red Self-electrochemiluminescence

The potential of CO 3 2− ligand in self-electrochemiluminescence (self-ECL) was exploited. The CO 3 2− unit can generate a coreactant radical and cause distortion of the structure to trigger an unusual electric-dipole transfer transition in 5 D 0 – 7 F 4 .
