Abstract
Abstract Boron gets its name from the term borax, the mineral from which it was originally isolated, by analogy with carbon due to their chemical similarities. Unlike its neighbor on the periodic table, however, boron only possesses enough valence electrons to form three covalent bonds. This means that organoboron compounds are inherently electron deficient and typically adopt a trigonal‐planar (sp 2 ‐hybridized) geometry with the empty p z orbital of boron lying orthogonal to the bonding plane. In this form, boron is isoelectronic and isostructural with a positively charged carbocation, which gives rise to many of the applications often associated with trivalent organoboranes (e.g., organic synthons and electron‐transport materials). Coordinatively saturating these systems with anionic or neutral Lewis bases yields tetrahedral, four‐coordinated boron compounds with a formal negative charge. This new bonding arrangement significantly alters the orbital composition of the resulting molecules, imparting new features such as intense charge transfer (CT) luminescence and, in some cases, unique photochemical reactivities such as photochromism or photoelimination. This chapter will document recent progress in photochemical transformation based on organoboron compounds. A brief overview of concepts related to photophysical and photochemical processes will be presented, followed by an introduction to photochromic systems and a comprehensive review of organoboron photochemistry. Several recently discovered classes of photoresponsive organoboron molecules and their potential applications will be presented.

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; both teacher heads agree on what is shown here.
