Tetraoctylphosphonium Tetrakis(pentafluorophenyl)borate Room Temperature Ionic Liquid toward Enhanced Physicochemical Properties for Electrochemistry
Bibliographic record
Abstract
Presented herein is the facile preparation of a new room temperature ionic liquid (RTIL), tetraoctylphosphonium tetrakis(pentafluorophenyl)borate (P(8888)TB). Subsequently, its physicochemical properties such as density, viscosity, and conductivity were characterized relative to temperature, demonstrating values of 1.22 g·cm(-3), 727 mPa·s, and 180 μS·cm(-1), respectively, at 60 °C. The electrochemistry of P(8888)TB was also investigated using cyclic voltammetry at a Pt-disk ultramicroelectrode and at a microinterface between water and the RTIL; this analysis revealed a wide metal-electrolyte potential window, ∼3.5 V, and a large liquid|liquid polarizable potential window, ∼0.9 V, at a temperature of 60 °C. Additionally, electron transfer (ET) reactions at a metal electrode|RTIL interface along with ion transfer (IT) reactions at the water|P(8888)TB interface were examined; the kinetics of these reactions were explored using finite element analysis. Increased ET and IT kinetics combined with enhancements of physicochemical properties versus RTILs we made previously seemingly suggest modest improvements. However, taken as a whole, they demonstrate significant progress toward a hydrophobic RTIL that can be used in conventional electrochemistry and biphasic metal ion extractions.

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.
