Forward‐ and Retro‐Vapofluorochromism of Sponge‐Like Macrocycle Crystals
Bibliographic record
Abstract
Achieving dynamic multicolor emission through solid-state molecular motion is of significant importance for advancing applications in organic solid-state luminescent materials. Herein, we report macrocycle crystals with unique forward- and retro-vapofluorochromic behavior, which is realized by reversible amine vapor uptake and amine-"squeeze" induced guest release. The forward-vapofluorochromism occurs when aliphatic amines penetrate guest-free macrocycle crystals to form host-guest complex crystals. These fluorescent properties can be reversibly toggled by exposing the amine-loaded crystals to another amine vapor through competitive guest replacement inside the crystals. Notably, retro-vapofluorochromism is achieved by exposing amine-loaded crystals to α-methylbenzylamine (MBA). Mechanistic studies show that MBA molecules do not penetrate the crystals, but rather "squeeze" the crystals to release loaded amines, driving the amine-loaded crystals back to the guest-free phase. The demonstrated forward- and retro-vapofluorochromism has already been successfully integrated into a highly secure five-layer information encryption system.

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.
