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

Organic molecular crystals enable spin alignment of triplet excitons over macroscopic distances, offering a molecular route to solid-state quantum technologies. In typical crystals, however, dense packing promotes spin decoherence through dipolar coupling and exciton hopping. Although dilution doping can mitigate these effects, reported examples remain scarce because dopants must satisfy stringent structural and energetic constraints. Here, we broaden the design space for doped organic crystals by introducing a strategy that employs a host-derived dopant with intramolecular charge-transfer (ICT) character that maintains structural compatibility with the host lattice, while its ICT character lowers the triplet energy to localize triplet excitons. Ultrafast transient absorption spectroscopy confirms triplet formation, while time-resolved electron paramagnetic resonance (TREPR) spectroscopy reveals that these oriented triplets possess selectively addressable spin sublevel transitions. Additionally, pulse-EPR measurements yield a phase memory time (T
