The development of novel, efficient and cost-effective emitters for solid-state lighting devices (SSLDs) is ubiquitous to meet the increasingly demanding needs of advanced lighting technologies. In this context, the emergence of thermally activated delayed fluorescence (TADF) materials has stunned the photonics community. In particular, inorganic TADF material-based compounds can be engineered by chemical modification of the coordinated ligands and the type of metal centre, allowing control of their ultimate photo-/electroluminescence properties, while providing a viable emitter platform for enhancing the efficiency of state-of-the-art organic light-emitting diodes (OLEDs) and light-emitting electrochemical cells (LECs).

- - The complex [Ag(IPr)(dpa)][PF] (1) was synthesized and characterized to explore its photophysical properties in comparison to [Cu(IPr)(dpa)][PF] (2), both intended for use in blue-emitting light-emitting electrochemical cells (LECs).
- - Key findings show that complex 1 emits fluorescence while complex 2 exhibits thermally activated delayed fluorescence, highlighting a shift in the nature of their emitting states due to the different metal ions used.
- - Additionally, complex 1 demonstrates varying emission based on its crystallinity in thin films and displays stable electrical performance in LECs lasting over 100 hours, a significant improvement over the few minutes of stability observed with complex 2.*
Article Synopsis
- * Designing ionic AIE emitters for light-emitting electrochemical cells (LECs) is crucial, focusing on creating structures that enhance ion polarizability for better charge injection and ensure reversible electrochemical behavior.
- * The study fine-tunes the balance between hydrophilic and hydrophobic properties in cationic tetraphenyl ethene (TPE) derivatives to improve their photoluminescence, redox behavior, and ion conductivity, resulting in enhanced performance for LECs
