Controlling C<sub>60</sub> Organization through Dipole-Induced Band Alignment at Self-Assembled Monolayer Interfaces
Bibliographic record
Abstract
Understanding the structural organization and growth of organic molecules on self-assembled monolayers (SAMs) is crucial for creating high-performance SAM-based electronic devices. We report herein C 60 adsorption onto benzenethiol (BT), pentafluorobenzenethiol (PFBT), and octanethiol (C8SH) SAM-modified Au(111) studied using scanning tunneling microscopy at the liquid–solid interface. A continuous film of C 60 molecules forms at a much faster rate ( k = 3.3 × 10 –7 s –1 ) on PFBT compared to that on BT ( k = 7.2 × 10 –9 s –1 ) and C8SH SAMs ( k = 9.5 × 10 –9 s –1 ). On the basis of density functional theory calculations, we propose that the difference in C 60 growth behavior originates from the dipole-induced dipole interactions between the SAM and C 60 . This may be further augmented by an inverse charge transfer from C 60 to SAM. This work provides new insights into the self-assembly behavior of next-generation electronic materials.

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.
