General description

Sodium 3-mercapto-1-propanesulfonate forms self assembled monolayer via chemisorption on a gold-coated substrate.

Application

Sodium 3-mercapto-1-propanesulfonate (MPS) can be used to prepare tetrasubstituted organosilicon thioether by photochemical reaction with tetravinylsilane via thiol-ene reaction. It can also be used as a capping agent to functionalize gold nanoparticles for potential applications in the field of radiotherapy and drug delivery.
MPS can be also used in the preparation of Rh nanoparticles by liquid-phase reduction of rhodium (III) chloride.

The chevron-shaped dye, N-butyl-2,6-bis-[2-{4-(2-(4-dibutylaminophenyl)-vinyl)-phenyl}-vinyl]-pyridinium iodide, has a hydrophilic apex that is electron-accepting and hydrophobic it-bridged limbs that are electron-donating. It forms non-centrosymmetric monolayers at the air-water interface and when deposited, its LB films exhibit second-harmonic generation and asymmetric current-voltage (I-V)
