Dynamic duo: the differential impact of resorcinarenes on ferrocene redox couple in electroactive host–guest systems
Bibliographic record
Abstract
Alternative to complex labelling of resorcinarene hosts with redox-active probes, noncovalent complex formation offers a unique avenue toward bifunctional hosts, which posses redox centers to transduce an electrochemical signal as well as maintaining a guest recognition site. Herein, N-alkyl ammonium resorcinarene halides (NARXs) hosts were evaluated with a well-known redox probe ferrocene (Fc). Specifically, the NARX hosts were designed based on the tuning of the resorcinarene upper rim to allow for hydrogen bonding, pi–pi stacking, ion and halogen binding interactions in organic environments. The NARX host induced a significant anodic shift of Fc E1/2; once formed, the Fc–NARX complex undergwent oxidation and reduction without Fc dissociation. Data indicate that hydrophobic interactions stabilize Fc interactions with the resorcinarene upper rim, which is directly related to the structural functionalization of the resorcinarene. Thus, we provide evidence for a controlled and tunable redox host–guest system with well-defined redox properties while maintaining the guest recognition site, suggesting that the host is bifunctional.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
