Outstanding Multi-Photon Absorption at π-Delocalizable Metallodendrimers.
Article in Angewandte Chemie (International ed. in English), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Multi-photon absorption (MPA) has attracted interest for applications exploiting the tight spatial control of interaction volume and long wavelength excitation. However, a deficiency of molecules exhibiting higher-order nPA (n-photon absorption, n>2) and a lack of structure-property studies to define the key structural characteristics needed to optimize higher-order MPA performance have hindered practical development. We herein report the syntheses of second- and third-generation metallodendrimers and assessment of their nonlinear absorption, together with those of zero- and first-generation analogues. We report the first 5PA and 6PA data for an organometallic. The largest dendrimer exhibits exceptional three-, four-, five- and six-photon absorption to femtosecond-pulsed light. The systematically varied compounds highlight the crucial role of metal-to-oligo(phenyleneethynylene) charge transfer in promoting outstanding MPA activity.
