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

Multi-resonance thermally activated delayed fluorescence (MR-TADF) emitters exhibit high photoluminescence quantum yields and exceptional color purity, driving significant interest in high-performance organic light-emitting diode (OLED) applications. Current strategies for constructing full-color MR-TADF emitters rely on intricate structural designs to regulate emission wavelengths, yet overlook critical photophysical parameters (such as emission maximum, excited-state lifetime, and so on) and obscure fundamental structure-property relationships, impeding precise control over photophysical behaviours. To address this issue, this study adopts a unique isomeric design strategy to reveal the basic emission properties of MR-TADF molecules. By systematically probing subtle connectivity differences within conserved mono-boron and dual-boron-based multi-resonant skeletons, the chemical bonding pattern dependent emission property was investigated. The critical factors affecting emission wavelength and excited-state lifetime have been uncovered. The detailed theoretical analyses provided a reasonable explanation for these results. This study establishes a molecular design strategy for precise optimization of emission properties, offering deep insights to facilitate the development of high-performance MR-TADF materials. Moreover, the exceptional device performance of compounds
