Description générale

Biphenyl-4,4′-dithiol (BPDT) is an aryl dithiol that is prepared by taking a mixture of stannous chloride dihydrate and glacial acetic acid with anhydrous hydrogen chloride. It forms a self-assembled monolayer on a variety of surfaces by attaching one thiol group to the surface while the other can create nucleation sites for other functional groups.

Application

BPDT can be used to functionalize iron nanoparticles (NPs) with the gold shell (Fe−Au) on polyethylene substrate. It can also be coated on the p-doped gallium arsenic (GaAs) substrate for a variety of semiconductor applications.

Precise Nanoparticles for Optoelectronics Applications

Inorganic nanomaterials are tunable by size, shape, structure, and/or composition. Advances in the synthesis of well-defined nanomaterials have enabled control over their unique optical, electronic, and chemical properties stimulating tremendous interest across a wide range of disciplines. This article illuminates some of the recent research advances of inorganic nanoparticles (NPs) in optoelectronics applications.

Micro and Nanometer Scale Photopatterning of Self-Assembled Monolayers

Self-assembled monolayers (SAMs) have attracted enormous interest for a wide variety of applications in micro- and nano-technology. In this article, we compare the benefits of three different classes of SAM systems (alkylthiolates on gold.
