Exploring the Impact of the Presence of 9,9′‐Spirobifluorene Moieties on the Performance of Carbonyl‐Based Multiresonant Thermally Activated Delayed Fluorescence Organic Light‐Emitting Diodes

open access: yesAdvanced Optical Materials, EarlyView.
The impact of decorating the multiresonant thermally activated delayed fluorescence (MR‐TADF) emitter DiKTa with 9,9′‐spirobifluorene units is explored with regard to number, position, and incorporation type. Four novel sky‐blue narrowband MR‐TADF emitters are developed, and in the OLED devices, a structure‐property relationship is observed with ...

Comparison of the Performance of Fluorescent, Phosphorescent, and TADF Luminophores for Explosives Sensing

open access: yesAdvanced Sensor Research, EarlyView.
Both singlet and triplet populations of the TADF compound 4CzIPN are quenched upon interaction with dinitrotoluene by photoinduced electron transfer. However, their quenching rate is different, with the triplet excitons being more efficiently quenched due to a combination of their longer lifetime and larger population.

Enhancing Voltage Tolerance of CsFA Perovskite‐Based Rectifying Diodes Through Ionic Liquid Incorporation

open access: yesAdvanced Sustainable Systems, EarlyView.
CsFAPbI3 perovskite diodes show superior low‐voltage rectification. Ionic liquid incorporation suppresses ion migration and enhances voltage tolerance, enabling durable performance for AC–DC conversion and other optoelectronic devices. Abstract Metal halide perovskites have gained significant attention owing to their remarkable semiconductor properties

Revealing the Character of Coordination Bonding in 2D Metal–Organic Frameworks

open access: yesAdvanced Science, EarlyView.
Photoemission‐derived momentum maps and density functional theory calculations show the re‐appearance of frontier molecular orbital patterns at two distinct binding energies, a result of the formation of bonding and antibonding states below the Fermi edge from covalent hybridisation with the metal centres.
