4-Mercapto-1-butanol
4-Mercapto-1-butanol (CAS: 14970-83-3), a sulfur-containing organic compound with the formula HS(CH2)4OH and a molecular weight of 106.19 g/mol, serves as a versatile building block in chemical synthesis. Its bifunctional nature, possessing both a thiol and a hydroxyl group, allows it to participate in diverse chemical reactions. This compound is particularly noted for its application in creating stable, concentrated nano-ink formulations for metal nanoparticles.
Nanoparticle Stabilization for Conductive Inks
4-Mercapto-1-butanol is employed to form hydrophilic sparse ionic monolayers on metal nanoparticles, such as gold and silver. This stabilisation is crucial for preparing highly concentrated nano-inks.
Sintering of Nanoparticle Inks
The stabilised nanoparticle inks can be sintered at relatively low temperatures (150 °C) to achieve near-bulk conductivity, enabling applications in printed electronics and conductive coatings.
Organic Synthesis Building Block
With both a thiol and a hydroxyl functional group, this compound acts as a valuable intermediate in organic synthesis, enabling the construction of more complex molecules.
Materials Science Applications
Its ability to form organised monolayers and its bifunctional nature make it suitable for surface modification and the development of novel self-assembly materials.
