Sourced in United States, Germany

1-dodecanethiol (DDT) is a long-chain alkanethiol molecule that is commonly used as a reagent in various laboratory applications. It serves as a precursor for the formation of self-assembled monolayers (SAMs) on metal surfaces. The primary function of DDT is to provide a stable, ordered, and densely packed organic layer that can be used for surface modification and functionalization purposes in research and development.

Synthesis of Bismuth Nanocrystals

Bismuth nanocrystals were synthesized according to Son, et al12 (link). Briefly, 3.6 grams (5 mmol) of bismuth neodecanoate (Sigma-Aldrich St. Louis, MO, USA) was combined with 25 mL of 1-octadecene (Sigma-Aldrich St. Louis, MO, USA). The mixture was then heated to 120 °C under a N2 atmosphere for 2 hours to remove water and dissolved oxygen. The mixture was then cooled to 80 °C with continuous stirring. 1.2 mL of 1-dodecanethiol (DDT) (Sigma-Aldrich St. Louis, MO, USA) was then added and the mixture was kept at 80 °C for 5 minutes. The addition of DDT caused the solution to change from colorless to yellow, indicating the formation of the bismuth dodecanethiolate complex. Next, 5 mL of tri-octylphosphine (Alfa Aesar, Heysham, England) was injected, causing the yellow solution to turn black. The reaction was then cooled and maintained at its growing temperature of 60 °C for 30 minutes with continuous stirring. The nanocrystals formed were then precipitated with a 10:1 (v/v) mixture of acetone/tetrahydrofuran (THF), and retrieved by centrifugation (17,000 g × 10 minutes) and washed several times with 10:1 (v/v) acetone/THF.

2 nm AuNPs were prepared using a method adapted from Brust et al.39 (link). Deionized (DI) water (resistivity 15 MΩcm) was used in all experiments. An aqueous solution of chloroauric acid trihydrate (VWR, UK) (6 mL, 30 mM) was mixed with tetraoctylammonium bromide (Sigma Aldrich, UK) (16 mL, 50 mM) in toluene (Fisher Scientific, UK). The mixture was vigorously stirred until the gold salt was completely transferred to the organic phase and 1-dodecanethiol (DDT) (Sigma Aldrich) (34 mg) was added. Freshly, prepared aqueous sodium borohydride (VWR, UK) (5 mL, 0.4 mM) was added dropwise and the solution was continuously stirred over a period of 3 h. The organic layer was subsequently extracted and evaporated to 2 mL. ethanol (80 mL) was added to the organic layer and stored for 4 h at −18 °C, after which the black precipitate was filtered off and washed with ethanol (Merck Millipore, UK). The freshly made nanoparticles were subsequently suspended in toluene for further use.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
