1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Multiple-resonance thermally activated delayed fluorescence (MR-TADF) emitters have attracted considerable interest due to their superiority in high-resolution organic light-emitting diodes (OLEDs), but suffer from severe aggregation-caused quenching and slow reverse intersystem crossing. Herein, a dynamic pendulum strategy is proposed, in which electron donors are tethered to the classic boron-nitrogen MR core (BCzBN) by employing an oxygen atom as a flexible anchoring point. Benefitting from the distinctive oxygen linkage and dynamic swinging behavior, the resultant MR-TADF emitters can access multiple isomeric conformations, thereby simultaneously achieving blue-shifted emission, preserved narrow full width at half maximum, enhanced quenching resistance, and faster spin flipping compared with BCzBN. As a consequence, the corresponding OLEDs achieve bright blue narrowband electroluminescence in an extremely wide doping window of 1-30 wt%, revealing a record-high external quantum efficiency of 30.4% even at 20 wt%. The results clearly highlight the great potential of the dynamic pendulum strategy for efficient blue MR-TADF emitters.
