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

We report a series of small-molecule acceptors Z1-Z4 that reconcile low non-radiative energy loss with efficient charge transport by combining a nitrogen-containing core with out-of-plane steric-hindrance/chlorination-regulated packing. The dibenzo[b,f]azepine unit enables low non-radiative energy losses below 0.20 eV, while progressive backbone unlocking and targeted chlorination reshape intermolecular packing by suppressing unfavorable core-centered aggregation and promoting multidimensional electronic coupling. Single-crystal analysis, GIWAXS, and electronic-structure calculations reveal enhanced packing coherence and stronger coupling pathways from Z1 to Z4. Transient absorption spectroscopy and kinetic analysis further show that improved exciton delocalization accelerates interfacial exciton dissociation and suppresses monomolecular recombination. Photo-induced force microscopy confirms more continuous acceptor-rich fibrils in Z3- and Z4-based blends. Consequently, the optimized Z4-based binary device achieves a PCE of 20.28% with a high open-circuit voltage of 0.95 V, demonstrating an effective molecular strategy for low energy-loss high-performance organic solar cells.
