Synthesis and Photodynamic Activity of Novel Asymmetrically Substituted Fluorinated Phthalocyanines
Bibliographic record
Abstract
A series of asymmetrically substituted dodecafluorinated phthalocyanines has been synthesized via the Kobayashi ring expansion reaction of the corresponding dodecafluorinated boron subphthalocyanine with differently substituted 1,3-diiminoisoindolines. The mild reaction conditions employed during this ring expansion reaction gave rise exclusively to 3:1 asymmetrically substituted dodecafluorinated phthalocyanines. Metal insertion into the metal-free phthalocyanines was accomplished by heating at 40 degrees C in N,N-dimethylformamide in the presence of zinc bromide. The resulting zinc dodecafluorophthalocyanines were formulated as Cremophor EL oil-water emulsions and evaluated as photosensitizers in vitro against EMT-6 mouse mammary tumor cells. As compared to the previously studied zinc hexadecafluorophthalocyanine, these new asymmetrical zinc dodecafluorophthalocyanines exhibited improved photodynamic activity.

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.
