Applications & Uses

Uses

n-octylbenzene is used as a solvent to study the self-assembly of derivatives of tetrathiafulvalene (TTF) on graphite and their visualization by scanning tunnelling microscopy (STM). It is also involved in the study the effects and substitution of these compounds. It is also used to prepare charge-transfer complexes with fluoranil and 1,3,5-trinitrobenzene.

Uses

1-Phenyloctane is used as a solvent to study the self-assembly of derivatives of tetrathiafulvalene (TTF) on graphite and their visualization by scanning tunnelling microscopy (STM). It is also used to study the effects of the substitution of these compounds on the interactions between them.

General Description

Octylbenzene (1-Phenyloctane) forms charge-transfer complexes with fluoranil and 1,3,5-trinitrobenzene.
