Abstract
The exploration of purely aliphatic optoelectronic macromolecules with elevated conductivity, emission efficacy, redox capacity, and solubility in aqueous media should extend the application prospects of optoelectronic polymers. Here, initially, four purely aliphatic (synthetic) electroactive luminescent polymers (ELPs), followed by four semisynthetic electroactive luminescent inclusion polymers (ELIPs), and finally, three metal ion-inclusion polymer (semisynthetic) networks (M(II/IV)-MIPN, M = Ni(II)/ Zn(II)/ Zr(IV)) are strategically designed and synthesized. For the first time, alike aromatic/ conjugated polymers, aliphatic luminescent polymers imparting conductivities in the range of 355.6–137.7 mS cm –1 are explored. Fourier transform infrared and nuclear magnetic resonance spectroscopies confirm the origination of cyclic aliphatic N -(5-methacryloyl-1,5-oxazocan-2-ylidene)- N -methylmethanaminium (MAOYMEMM) ion comprising an oxazocane ring during the synthesis of ELPs, ELIPs, Zr(IV)-MIPN, Ni(II)-MIPN, and Zn(II)-MIPN. In ELP3/ ELIP3 (optimum composition), Zr(IV)-MIPN, Ni(II)-MIPN, and Zn(II)-MIPN, spontaneous charge-/ electronic-transport from the electron rich oxyanion of −C(−O – )═N + (CH 3 ) 3 in N, N -dimethylacrylamide to the electronically deficient carbonyl carbon in MAOYMEMM endows optical and electrical properties. In ELIP3/ Ni(II)-MIPN, β-cyclodextrin-/ Ni(II)-associated 333.71/ 242.44% enhancement in charge transfer efficacy is indicated from dual-state UV–vis and luminescence spectroscopies. Here, impedance measurements and cyclic voltammetric analyses of M(II/IV)-MIPN-modified glassy carbon electrodes (GCE) (GCE|Zn(II)-MIPN and GCE|Zr(IV)-MIPN) confirm the highest conductivity and oxidizing ability of Zn(II)-MIPN and Zr(IV)-MIPN, respectively. Finally, optoelectronic Zr(IV)-MIPN, Ni(II)-MIPN, and Zn(II)-MIPN showing the maximum open circuit potential (1.05 V vs Ag/AgCl), 242.44% enhancement of CT, and ultrahigh conductivity (355.6 mS cm –1 ) are employed as efficient cyclic voltammetric (limit of detection (LOD) = 3.77 μM), luminometric (LOD = 3.64 nM), and impedimetric (LOD = 5.62 μM) glucose sensors, respectively. The significant efficiencies of multimethod sensing performed with Zr(IV)-MIPN, Ni(II)-MIPN, and Zn(II)-MIPN are indicated by high selectivity, sensitivity, stability, reproducibility, and appreciably low LODs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
