Integrity Concerns Review: 'Hierarchical Chirality Memory Governs Dual Chiroptical Inversion in Mesoscopic Helical Covalent Organic Frameworks' (DOI: 10.1002/anie.5082047)

Academic fraud report · Geng Detector

Summary

This report reviews a 2026 Angewandte Chemie International Edition paper by Zhenzhen Jiang, Xinlin Zha, Mengjuan Zuo et al. (Wuhan Textile University / King Fahd University of Petroleum and Minerals) and assigns an overall verdict of 'highly suspicious' pending original data. Three findings were verified verbatim against the text: (1) the main text places Figure 6d at 30 min while the figure caption states 15 min, undermining the time-series core of the chirality-memory kinetic argument; (2) reference 19 contains a corrupted author field ('Z. X. T. Dendrimers'), consistent with reference-manager errors; (3) a sentence in the DFT discussion appears twice verbatim. Additionally, programmatic copy-move (Fridrich block-matching) analysis flagged at least six embedded SEM/spectra figures with same-offset matching blocks (e.g., img-002 offset (0,40), 47 pairs; img-004 (32,0), 14 pairs), though offsets match panel spacing and remain unconfirmed without original images. A reported numerical statistical finding was removed during review because its data were not from the paper and its test premises were unsatisfied. The automated Bayesian synthesis (posterior ≥99.9%) should be treated with caution due to conditional-independence assumptions. Final determination requires institutional investigation and author-provided raw SEM data.

Verdict

Highly suspicious (pending verification) — The three textual findings are confirmed verbatim in the source. The copy-move image signals are strong leads but require original SEM data for confirmation. Final determination of misconduct requires institutional investigation.

Key findings

Text–caption time contradiction (confirmed, 🟠): Main text states the R-2,3-COP-2 system at "30 min" forms well-defined left-handed helical structures in Figure 6d, but the caption reads "(b) 5 min, (c) 10 min, (d) 15 min, and (e) 1 h" — Figure 6d corresponds to 15 min. This time series is central to the paper's kinetic chirality-inversion argument. A typographical error is possible, but no correction or explanation exists in the paper.
Corrupted reference field (confirmed, 🟡): Reference 19 lists authors as "F. Li, X. Li, Y. Wang, and Z. X. T. Dendrimers" — the journal name "Dendrimers" is misplaced into the author field. Likely a reference-manager artifact; individually insufficient to establish misconduct.
Verbatim duplicated sentence (confirmed, 🟡): "The overall trimer adopts a clockwise stacking configuration." appears twice consecutively in the Figure 5 DFT discussion, suggesting copy-paste editing residue or a typesetting accident.
Copy-move image signals (unconfirmed lead, 🟠): Fridrich block-matching detected same-offset exact-matching blocks in at least six embedded images: img-002.jpg offset (0,40), 47 pairs; img-004.png offset (32,0), 14 pairs; img-005.jpg offset (80,0), 10 pairs; img-006.jpg; img-009.jpg offset (32,0), 16 pairs; img-011.jpg offset (48,0), 21 pairs; several also show inconsistent noise variance.
Removed finding: A numerical statistical test (original finding 5) was deleted on review because its data points were not from the paper and the test premises were unsatisfied.

Evidence highlights

Verbatim text match: main text "polymerization to 30 min … (Figure6d)" vs. caption "(d) 15 min" — contradiction confirmed by character-level comparison.
Copy-move matches are consistently aligned with multi-panel spacing (vertical 40 px; horizontal 32/48/80 px), a candidate benign explanation (regular panel elements produce same-offset matches), but the paper provides no layout or image-processing documentation to support this; the explanation remains speculative.
If Figure 6 time-series SEM panels contain duplicated content, it would directly undermine the "chirality memory" kinetic narrative and would echo the time-annotation contradiction.
Automated Bayesian synthesis reports posterior ≥99.9%, 95% credible interval [100%, 100%], BF = 1.17e+9, based on fixed 5% prior and conditional-independence assumptions (LR version geng_lr_v3, n=11 calibration) — this may overstate joint strength of correlated evidence and does not constitute a misconduct finding.

Notes

The paper is dated 2026 (Received: 26 May 2026; Accepted: 20 July 2026), which could not be independently verified here.
Recommended follow-up: request original Figure 6 SEM files and acquisition metadata from authors; request clarification of the 30 min vs. 15 min discrepancy; request un-composited original images for the six flagged figures; consider posting annotated evidence on PubPeer and notifying the journal editorial office, escalating to institutional review depending on the response.
