1-Adamantanethiol is primarily used in the field of nanotechnology and materials science. It serves as a key component in the formation of self-assembled monolayers (SAMs) on gold surfaces. These SAMs are crucial for creating highly ordered, stable, and functional surfaces that are utilized in various applications such as biosensors, molecular electronics, and surface coatings. The thiol group in 1-Adamantanethiol allows it to bind strongly to gold, while the adamantane structure provides rigidity and stability to the monolayer. This makes it particularly useful in designing surfaces with specific chemical and physical properties for advanced technological applications. Additionally, it is employed in organic synthesis as a building block for more complex molecules, particularly in the development of pharmaceuticals and materials with unique properties.
