Chiral dual-annihilator model for controllable photon upconversion and multi-dimensional optical modulation.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Triplet-triplet annihilation photon upconversion seeks efficient conversion of low-energy photons to high-energy emission. However, the triplet-triplet annihilation photon upconversion system faces limitations in emission gamut because efficient triplet-triplet energy transfer between sensitizer and annihilator relies on triplet energy matching, making it challenging to realize multi-channel luminescence and multi-dimensional optical control. Here, to overcome this barrier, we propose a chiral dual-annihilator model, which mitigates the restriction of energy matching and achieves facile manipulation of circularly polarized luminescence through a dual-channel triplet-triplet energy transfer process. A theoretical equation for quantifying the overall triplet-triplet energy transfer efficiency and the energy flow between the sensitizer and two kinds of annihilators is proposed. Its accuracy is demonstrated by fine-controlling the emission bandwidth of triplet-triplet annihilation photon upconversion (average error less than 4.5%) in the experimental aspect. In addition, by introducing chiral liquid crystals, the dual-annihilator model achieves data coding and multi-dimensional optical encryption applications. This dual-annihilator model deepens the understanding of energy flow and lays the foundation for accurate, multidimensional modulation of photon upconversion.
