General description

Dibenzotetrathiafulvalene (DBTTF) is an organic semiconductor that is completely conjugated with a symmetric structure. It forms stacks of planar molecules with a distance of 3.948 Å. DBTTF has a high mobility of charges and can be prepared from anthranilic acid and purified by sublimating in vacuum.

Application

DB-TTF is used to make semiconducting charge transfer salts with electron accepting (n-type) materials, for example TCNQ (Aldrich Prod. No. 157635) and F4TCNQ (Aldrich Prod. No. 376779 ).
DBTTF is an organoelectronic material that forms a charge transferring complex with a variety of semiconducting crystals which include 7,7,8,8-tetracyanoquinodimethane (TCNQ) and 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ). These materials can be in the form of single crystals and thin films for the fabrication of organic field effect transistors (OFETs) and organic light emitting diodes (OLED).
