Ru(II) polypyridine complexes: photophysics, photochemistry, eletrochemistry, and chemiluminescence

Blue organic light-emitting diodes that harness thermally activated delayed fluorescence are realized with an external quantum efficiency of 19.5% and reduced roll-off at high luminance.

Efficient blue organic light-emitting diodes employing thermally activated delayed fluorescence

Organic materials that exhibit thermally activated delayed fluorescence (TADF) are an attractive class of functional materials that have witnessed a booming development in recent years. Since Adachi et al. reported high-performance TADF-OLED devices in 2012, there have been many reports regarding the design and synthesis of new TADF luminogens, which have various molecular structures and are used for different applications. In this review, we summarize and discuss the latest progress concerning this rapidly developing research field, in which the majority of the reported TADF systems are discussed, along with their derived structure–property relationships, TADF mechanisms and applications. We hope that such a review provides a clear outlook of these novel functional materials for a broad range of scientists within different disciplinary areas and attracts more researchers to devote themselves to this interesting research field.

Charge-transfer absorption and emission of Cu(NN)2+ systems

The title compound, [Cu(dpp)2]+(dpp = 2,9-diphenyl-1,10-phenanthroline), exhibits long-lived emission at room temperature in solution, and in contrast with copper(I) complexes of less bulky ligands, the emission persists in polar media; a water soluble derivative of [Cu(dpp)2]+ is luminescent at room temperature in aqueous solution and undergoes efficient redox photochemistry in the presence of electron acceptors.
