The research strategy described in this manuscript harnesses the attractive properties of hydrogels, gold nanorods (Aurods), and magnetic nanoparticles (MNPs) by synthesizing one unique multi-responsive nanostructure. This novel hybrid structure consists of silica-coated magnetic particles encapsulated within a thermo-responsive...

Robust carboxylic acid-terminated organic thin films and nanoparticle protectants generated from bidentate alkanethiols.

A new carboxylic acid-terminated alkanethiol having bidentate character, 16-(3,5-bis(mercaptomethyl)phenoxy)hexadecanoic acid (BMPHA), was designed as an absorbate and protectant to form thermally stable carboxylic acid-terminated organic thin films on flat gold and nanoparticles, respectively. The structural features of the organic...

Inhibiting Reductive Elimination as an Intramolecular Disulfide Dramatically Enhances the Thermal Stability of SAMs on Gold Derived from Bidentate Adsorbents.

Langmuir : the ACS journal of surfaces and colloids

Rittikulsittichai S, Park CS, Marquez MD, Jamison AC, Frank T, Wu CH, Wu JI, Lee TR.

The bidentate aromatic adsorbate, 5-(octadecyloxy)-1,3-benzenedimethanethiol (R1ArmDT), with a specific design of extended S-S distance and a geometric constraint to resist cyclic disulfide formation was synthesized. The film formation and thermal stability of self-assembled monolayers (SAMs) derived from R1ArmDT were...

Bidentate Aromatic Thiols on Gold: New Insight Regarding the Influence of Branching on the Structure, Packing, Wetting, and Stability of Self-Assembled Monolayers on Gold Surfaces.

A series of 2-phenylpropane-1,3-dithiol derivatives with single (R1ArDT), double (R2ArDT), and triple (R3ArDT) octadecyloxy chains substituted at the 4-, 3,5-, and, 3,4,5-positions, respectively, on the aromatic ring were synthesized and used to form self-assembled monolayers (SAMs) on gold. Insight...

Tridentate adsorbates with cyclohexyl headgroups assembled on gold.

Langmuir. 2013 Jan 15;29(2):561-9. doi: 10.1021/la303101x. Epub 2013 Jan 03.

The tridentate adsorbates cyclohexane-cis,cis-1,3,5-triyltrimethanethiol (CyTSH) and (cis,cis-1,3,5-trimethylcyclohexane-1,3,5-triyl)trimethanethiol (3C1CyTSH) were designed and synthesized. Thin films prepared by the adsorption of these molecules onto the surface of gold were characterized by ellipsometry, contact angle goniometry, polarization modulation infrared reflection absorption spectroscopy,...
