Ju’s group found a dual excited states-mediated electrochemiluminescence (ECL) mechanism from both the S1 and T1 species with black phosphorus quantum dots (BPQDs) as a nanoemitter, and proposed a strategy to modulate the excited states via arginine modification to enhance the ECL efficiency.

By combining electricity and Pd catalysis, the first example of an asymmetric allylic pyrdinylation reaction was reported with 4-CN-pyridne as the pyridine source. The Pd catalyst acts not only as the transition-metal catalyst but also as an electron-transfer catalyst.
