Quadruple Helix Inversions of Liquid Crystals Orchestrated by Direct Chirality Transmission of an Intrinsically Chiral Light-Driven Molecular Machine.
Article in Advanced materials (Deerfield Beach, Fla.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Endowing liquid crystal (LC) soft matter with stimuli-responsiveness is pivotal for programmable and dynamic photonics in the next generation of optical materials. However, suitable molecular candidates with intrinsic dynamic chirality that can twist LC helices using external stimuli in a multistate, distinct manner are still very rare. In this study, an elaborately designed intrinsically chiral molecular machine is presented with four-state dynamic chirality and mesogenic units. This design enables direct chirality transmission, leading to sequential quadruple helix inversions of the LC architecture via unidirectional rotary motion, achieving a high helical twisting power in all states. The inversion of the supramolecular helicity by near-infrared (NIR) light is demonstrated by NIR light-triggered isomerization of the molecular motor structure through an efficient radiative energy transfer pathway from upconversion nanoparticles in the LC film. Hence, these results demonstrate a unique photoresponsive LC system with high robustness, NIR light triggering, and multistate helix tunability with a fascinating potential for constructing smart optical devices.
