Chemical Properties

1,8-Octanedithiol has a sulfurous, meaty odor. FEMA indicates that total dithiol added to any food should not exceed 1.0 ppm

Uses

OCT may be used as a processing additive that can functionalize the electrode layer to enhance the power efficiency of P3HT:PCBM solar cells. It may also be used to form a SAM on gold electrodes to enhance the electrochemical properties.

Definition

ChEBI: 1,8-Octanedithiol is an alkanethiol.

General Description

1,8-Octanedithiol (OCT) is an alkanedithiol, which forms a self-assembled monolayer (SAM) on a variety of metal surfaces. OCT contains linearly arranged carbon-carbon bonds (C?C) and two sulfur atoms at the end facilitating the attachment with the surface atoms of the substrates. It mainly forms an organo-metallic system, which can be used to improve the electron transport medium for a wide range of electronic applications.
