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

Nearly amorphous conjugated polymers, though lacking long-range order, can exhibit high charge carrier mobility and enhanced flexibility, making them ideal for flexible or stretchable OFET applications. However, research on novel structural blocks for this class of materials remains limited. We report the synthesis of two derivatives of the 5,10-dihydroindeno[2,1-a]indene (DHI) core, where two thieno groups are appended to each end to reduce torsional disorder with adjacent comonomers. The two 1,4-dihydropentalene containing isomers, anti-C16DHIT-Br and syn-C16DHIT-Br, feature distinct thieno group orientations, leading to differences in their electronic properties. The anti-isomer shows a fully delocalized conjugation pathway, whereas the syn isomer exhibits cross-conjugation, limiting delocalization along the polymer backbone. These monomers were copolymerized with benzothiadiazole (BT) to form two conjugated polymers, anti-C16DHIT-BT and syn-C16DHIT-BT, both with highly planar backbones, good solubility, and solution processability. Morphological studies reveal that anti-C16DHIT-BT exhibits more ordered stacking and higher crystallinity than syn-C16DHIT-BT. Devices based on anti-C16DHIT-BT show significantly better performance, with a hole mobility of 2.38 cm
