Abstract
Retina-inspired neuromorphic systems require seamless integration of light sensing and adaptive synaptic modulation, yet conventional materials fail to integrate ionic charge transport with optoelectronic signal processing. Organic iono-optoelectronic devices offer a promising solution by coupling the optoelectronic properties of conjugated polymers with ionic and electronic transport. Here, we present an organic iono-optoelectronic synapse enabled by a p-type mixed ionic-electronic conductor (OMIEC). The OMIEC material, gDPP-MeOT2, a donor-acceptor polymer comprising a thiophene-flanked diketopyrrolopyrrole acceptor and methoxy-bithiophene donor, serves simultaneously as a light absorber and an ion reservoir, enabling light-modulated mixed charge transport. Our iono-optoelectronic synapse exhibits broad-band light detection spanning the visible to near-infrared range and synaptic plasticity features central to learning processes of the human brain. These results suggest that OMIECs can unify light detection, logic operation, and energy-efficient information processing, paving the way for next generation biohybrid vision systems and bio-inspired neuromorphic electronics.

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
