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).
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.
