A Donor-Acceptor-Type Two-Dimensional Poly(Arylene Vinylene) for Efficient Electron Transport and Sensitive Chemiresistors.
Article in Angewandte Chemie (International ed. in English), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Two-dimensional (2D) conjugated polymers and their layer-stacked 2D conjugated covalent organic frameworks, such as 2D poly(arylene vinylene)s (2D PAVs), are emerging as promising polymer semiconductors for electronics and photocatalysis. However, achieving narrow optical band gaps and efficient electron transport remains a significant challenge for this class of materials to enhance the device's performance. Here, we report a donor-acceptor-type 2D PAV (2DPAV-TBDT-IT, where TBDT = thienyl-benzodithiophene and IT = s-indacene-1,3,5,7(2H,6H)-tetraone) synthesized via an Aldol-type 2D polycondensation approach. Notably, 2DPAV-TBDT-IT benefits from an effective intralayer donor-acceptor effect, exhibiting an optical band gap of 1.15 eV, the smallest among the reported 2D conjugated polymers. Density functional theory calculations reveal a unique electron-dominating transport for 2DPAV-TBDT-IT, with a strongly dispersive conduction band minimum and, thus, a small effective mass for electrons half that for holes. Additionally, terahertz spectroscopy measurements indicate a high charge mobility of 26 cm
