Exploring the Synthesis and Electronic Properties of Axially Substituted Boron Subphthalocyanines with Carbon‐Based Functional Groups
Bibliographic record
Abstract
With peripheral fluorination and chlorination known to significantly influence the solubility, fluorescence quantum yield and redox properties of boron subphthalocyanines (BsubPcs), it is the intent of this study to further expand a matrix of BsubPcs to correlate structural changes to properties. Here, we have adapted previous synthetic methodologies for accessing axially substituted BsubPcs with a variety of alkyne substituents along with incorporating various peripheral halogens. While axial substitution of BsubPcs results in minimal shifts of longest‐wavelength absorptions, relative fluorescence quantum yields decrease with the increasing number of axial carbon–carbon triple bonds. Cyclic voltammetry studies reveal that BsubPcs can form a radical anion more easily with each additional carbon–carbon triple bond, the most significant change happening when going from one to two triple bonds. Also, the reduction profile is influenced by peripheral halogenation as well as by the radical‐stabilizing ability of an axial arylethynyl group. In all, axial alkyne‐based substituents have influential impact on the characteristics of BsubPcs.

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.
