The solution-phase thermal desorption of three series of self-assembled monolayers (SAMs) on gold generated from terminally perfluorinated alkanethiols was examined. Series 1 SAMs, F(CF2)x(CH2)11SH, where x = 1–10, consisted of a constant hydrocarb

A self-assembled monolayer of CF 3 (CF 2 ) 3 (CH 2 ) 11 NH 2 atop the (001) surface of the high-temperature superconductor YBa 2 Cu 3 O 7-x was imaged by atomic force microscopy (AFM). The AFM images provide direct 2D-structural evidence for the epit

Compositionally mixed, self-assembled monolayers (SAMs) derived from 16,16,16-trifluorohexadecanethiol and a normal alkanethiol, either hexadecanethiol or pentadecanethiol, were formed on Au(111) substrates. The relative composition of the films was

Highly branched photoluminescent polyphenylenes (PP) containing 1,3,5-triphenylbenzene (TPB) fragments were prepared via combination of cyclocondensation of acetylaromatic compounds and Ni0-catalyzed dehalogenation. To develop optimal conditions for

We demonstrate that it is possible to achieve exceptionally fine control over the anchoring of liquid crystals via the use of semi-fluorinated self-assembled monolayers of varying spacer length. We use this approach to map the detailed shape of an an

Self-assembled monolayers (SAMs) formed from alkyl-terminated, CF 3 -terminated, CF3CF2-terminated, and C 1 0 F 2 1 -terminated alkanethiolates on gold substrates were examined by low-energy (eV) ion-surface collisions to determine the impact of vary

The structures of semifluorinated alkanethiol self-assembled monolayers (SAMs) generated by the adsorption of CF3(CF2)9(CH2)nSH (F10HnSH, n = 2, 6, 11, 17, 33) onto gold were investigated with atomic force microscopy (AFM), X-ray photoelectron spectr
