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

The cyano group is extensively employed in the molecular engineering of high-performance small-molecule acceptors (SMAs) for organic solar cells (OSCs) to fine-tune energy levels and optimize molecular packing. To date, the application of cyano group has predominantly been confined to end-group modification in SMAs, with limited investigation in central unit engineering. Herein, in this work, the role of cyano substitution is systematically investigated in the central unit of SMAs and design a novel cyano-functionalized wide-bandgap acceptor UF-BCN. The introduction of the cyano group significantly enhances the surface energy of the molecule and substantially deepens the highest occupied molecular orbital (HOMO) energy level due to its strong electron-withdrawing capability, then leading to a blue-shifted absorption. When introduced as the third component in the D18:BTP-eC9, UF-BCN demonstrates complementary light absorption, strong intermolecular interactions, and excellent compatibility with BTP-eC9 to form a mixed acceptor phase, enabling it to function as an effective morphological modulator within the ternary system. Consequently, the ternary OSC based on D18:BTP-eC9:UF-BCN achieves an impressive power conversion efficiency (PCE) of 19.34%. This study underscores the effectiveness of cyano substitution in central unit engineering and highlights its potential for optimizing active layer morphology and enhancing the performance of ternary OSCs.
