Dipyrromethene Boron Complex for High Quantum Yield and Moisture Resistance

The patent changes the coordination mode of the dipyrromethene ligand to boron from bidentate to tridentate or tetradentate, and modifies the chemical structure by introducing specific substituents (such as fluorine atoms at positions 2 and 7 of the dipyrromethene skeleton). These parameter changes in molecular structure and coordination chemistry resolve the contradiction by achieving high quantum yield while simultaneously improving light fastness and moisture-heat resistance.

The patent employs organic dipyrromethene boron complex compounds with tridentate or tetradentate coordination modes, which provide high quantum yield and color conversion efficiency. These compounds can be processed using conventional manufacturing techniques for LED phosphors, thus maintaining ease of manufacture while significantly improving energy efficiency and color conversion performance compared to traditional inorganic phosphors.
