Tuning the Work Function of Gold with Self-Assembled Monolayers Derived from X−[C6H4−C⋮C−]nC6H4−SH (n = 0, 1, 2; X = H, F, CH3, CF3, and OCH3)
Abstract
Changes in the work function of gold, ΔΦ Au, induced by the formation of chemisorbed self-assembled monolayers derived from the series of titled arenethiol adsorbates X − (C 6 H 4 − C⋮C−) n C 6 H 4 −SH ( 1, n = 0; 2, n = 1; 3, n = 2) have been measured by the Kelvin probe method. An analysis of these data indicates that variation in work function for a given chain length can be effectively modeled with two dipole sheets, as has been shown for other classes of self-assembled monolayers. Importantly, it is shown that monolayers of class 1 produce larger relative changes in work function for a given substituent X than those of either 2 or 3, presumably as a result of the larger polarizability of the longer chains present in the latter. Accordingly, these commercially available adsorbates are attractive for use in device applications requiring work function modification.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
