Syntheses of Bioinspired Trisporphyrin Scaffoldings from Stepwise Suzuki Coupling Strategies
Bibliographic record
Abstract
This review presents the synthetic approach for the design of tris(macrocycles) as bio-inspired models for light harvesting devices in plants and photosynthetic bacteria based on cofacial bisporphyrins and a porphyrin unit attached as a side arm. Two types of tris(porphyrins) are described herein depending on the nature of the chromophores of the cofacial bis(porphyrins). The synthetic methodology of a series of trimeric models relies on the versatility of the porphyrin ring acting as a building block, and on successive Suzuki coupling reactions. Various pathways to access such models are presented as the selective and stepwise substitution processes involving different borylated porphyrin synthons can provide either meso-meso-linked linear intermediates or cofacial homo-or hetero-bismacrocycle units. This efficient methodology also allows for the flexibility and fine tuning since different bridges and spacers can be used in the designed trimers.

How this classification was reachedexpand
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.
