Conjugated Polymers Bearing Iridium Complexes for Triplet Photovoltaic Devices
Bibliographic record
Abstract
The aim of this work is to investigate the effect of incorporating an iridium complex into a π-conjugated polymer backbone on photovoltaic properties such as charge generation, power conversion efficiency and external quantum efficiency (EQE). Poly(9,9-dihexylfluorene-co-2-phenylpyridine) ( 1 ) and poly(9,9-dioctylfluorene-co-tris(2-phenylpyridine) iridium (III))) ( 2 ) were synthesized using Suzuki polycondensation. Characterization was performed using NMR, UV−vis, photoluminescence, and time-resolved luminescence spectroscopy; gel permeation chromatography; elemental analysis; and photovoltaic devices. An increase in percent EQE for 2 over 1, from 1.1 to 10.3, is attributed to the formation of the triplet state in ( 2 ), and by inference, longer diffusion lengths of the triplet exciton, compared to the singlet exciton that is formed in ( 1 ).

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
