Trisilane was purchased from Voltaix, and stored in a glovebox (oxygen level < 0.1 ppm). N,N′-diisopropylcarbodiimide (99%), silicon tetrachloride (99%), butyl-lithium (2.5 m in hexane), n-hexane (anhydrous 95%), chloroform, and absolute ethanol were purchased from Sigma-Aldrich and used without further purification. Toluene and THF were dried using an Innovative Technology solvents purification system, then oxygen was removed by three freeze–pump–thaw cycles. The purified solvents were stored over 3 Å molecular sieves in an argon filled glovebox.
Butyl lithium
Manufactured by Merck Group
Butyl-lithium is a highly reactive organometallic compound commonly used as a strong base and nucleophile in organic synthesis. It is a clear, colorless liquid that is typically handled and stored under inert conditions due to its high reactivity. The core function of butyl-lithium is to facilitate various chemical transformations, such as alkylation, deprotonation, and metal-halogen exchange reactions, which are important steps in the synthesis of a wide range of organic compounds.

All synthetic procedures and handling of the chemicals for the nanostructure synthesis have been carried out using Schlenk techniques or an argon-filled glove box (MBraun). Butyl lithium, hexamethyldisilazane, SnCl2, 1,1,3,3-tetramethyldisilioxane, and GeCl4 were purchased from Sigma-Aldrich. All solvents for the precursor synthesis were dried using standard procedures and stored over molecular sieve. Precursors and intermediates have been prepared as described before.49 Dodecylamine (98%, Sigma-Aldrich) was distilled three times under reduced pressure using additions of 0.5–1 mL of Sn(N(Si(CH3)3)2)2 as described in literature.44 This procedure allows separation of impurities that can react with Sn(N(Si(CH3)3)2)2 and Ge(N(Si(CH3)3)2)2 in the following material synthesis and ensures the most reliable results.
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.
