Zusammenfassung vom Kontext und den Gesamtzielen des Projekts

Lighting accounts for ca. 20% of worldwide electricity consumption. By switching towards more energy-efficient lighting technologies a considerable amount of energy would be saved. Organic Light-Emitting Diodes (OLEDs) have been championed as a technology that can replace conventional inefficient lighting. With respect to the fluorescent tube, OLEDs are cheaper, mercury-free, have much cooler operational surface temperatures (30°C as opposed to 90°C), use less power, have a lower risk of fire and open up new avenues for product design (transparent lighting panels and luminescent wallpapers).

The main advantage of using thermally activated delayed fluorescence (TADF) emitters is that they are significantly cheaper to make and are far more sustainable a material than organometallic phosphors. Recently, significant progress has been made with blue and green TADF OLEDs, with device EQEmax exceeding 30%. Unfortunately, the performance of red TADF OLED devices (λEL > 600 nm; Commission Internationale de L’Éclairage, CIE, of x ≥ 0.60 y ≤ 0.40) are still suboptimal due to the low EQEs (<13%) and the significant energy roll offs. Indeed, only a handful of examples of red TADF emitters have been reported. It is now of paramount importance that attention is focussed towards the development of high-performance red TADF OLEDs.

The major focus of this research proposal is to develop high-performance red TADF dyes. These emitters will be used as principal components in white-light OLEDs

Arbeit, die ab Beginn des Projekts bis zum Ende des durch den Bericht erfassten Berichtszeitraums geleistet wurde, und die wichtigsten bis dahin erzielten Ergebnisse

As indicated in the report, partial synthesis of the proposed targets was completed along with preliminary DFT calculations. Due to the premature termination of the project due to the dismissal of the fellow there has been only a limited amount of progress made.

Fortschritte, die über den aktuellen Stand der Technik hinausgehen und voraussichtliche potenzielle Auswirkungen (einschließlich der bis dato erzielten sozioökonomischen Auswirkungen und weiter gefassten gesellschaftlichen Auswirkungen des Projekts)

As indicated above, due to the premature termination of the project, no progress beyond the state of the art exists.
