AI Technical Summary
Traditional iridium complexes are prone to aggregation and quenching in the solid state or at high concentrations, have poor hydrophobicity, and are prone to phase separation or luminescence quenching when complexed with natural polymers. Existing technologies have failed to effectively synergize their optical advantages and film-forming properties.
Iridium complexes were designed and synthesized by modifying the ligands of iridium complexes with long alkyl chains, and then combined with natural polymer materials such as chitosan or sodium alginate to regulate their photophysical properties, thus preparing iridium complex/natural polymer composite materials.
The problem of aggregation fluorescence quenching in iridium complexes has been solved, improving the hydrophobicity, film uniformity, and photophysical properties of the composite material. This results in high-intensity, tunable, and stable luminescence, making it suitable for flexible OLED devices and biocompatible optical sensors.
