Formation of long-range-ordered self-assembled monolayers of dodecyl thiocyanates on Au(111) via ambient-pressure vapor deposition

Molecular Self‐Assembly of Phenylselenyl Chloride on a Au(111) Surface

“…Self‐assembled monolayers (SAMs) prepared by adsorption of organic molecules onto metals have been the subject of enormous scientific interest because they provide a convenient route for tailoring the surface and physical properties of metals 1–3 . Such properties are controlled simply through appropriate selection of absorbate chemical structure, such as the headgroup and/or terminal functional group 1–18 . This advantageous trait enables SAMs to be utilized in a wide array of applications, such as surface wetting, biosensors, nanolithography, and electronic devices 1–4 .…”

“…New SAM precursors may provide novel opportunities for practical application of SAMs. To this end, numerous studies have been performed to probe the formation, structure, and physical properties of SAMs on gold that are prepared by other sulfur (S)‐containing precursors, such as protected thiols, 5,9 thiosulfates, 10 thiocyanates, 11–14 dithiocabamates, 15,16 and sulfenyl chloride 17,18 …”

[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] This advantageous trait enables SAMs to be utilized in a wide array of applications, such as surface wetting, biosensors, nanolithography, and electronic devices. [1][2][3][4] SAMs derived from organic thiols or disulfides on Au(111) have been extensively studied due to their high structural order and chemical stability resulting from strong chemical interactions between the sulfur headgroup and the gold surface.…”

Self‐Assembled Monolayers of Alkanethioacetates on Au(111) in Ammonium Hydroxide Solution

“…1,2,19,24,25 However, one drawback to using thiols is that in solution they can readily transform by oxidation to disulfides or sulfonate during SAM formation. 8,[27][28][29] To minimize this undesirable side reaction, other precursors such as chemically stable thiocyanates [30][31][32][33][34][35] or acetylprotected thiols (thioacetate) 26,27,29,[36][37][38][39][40][41][42][43][44][45][46][47][48][49][50] have been developed for SAM preparation. Various acetyl-protected thiols in particular have often been used for the preparation of SAM-based electronic devices via in situ deprotection of acetyl groups.…”
