DITHIENO[2,3-B:2',3'-D]THIOPHENE Chemical Properties,Usage,Production

Chemical Properties

Yellow to red solid

Uses

DTT can be used for a wide range of applications which include electro-luminescence, organic thin film transistors, photochromism, and organic photovoltaic (OPV) solar cells.

General Description

Dithieno[3,2-b:2′,3′-d]thiophene (DTT) is a conductive material that acts as a donor building block for synthesizing a variety of optoelectronic materials. It can be used as an active layer with high charge mobility and environmental stability for development of organic electronic devices.

Synthesis

502764-53-6

3593-75-7

General procedure for the synthesis of dithieno[3,2-b:2',3'-d]thiophene-2,6-dicarboxylic acid from dithieno[3,2-b:2',3'-d]thiophene: 113.0 g (0.397 mol) of the compound denoted by Eqs. 3-d, 24.0 g (0.378 mol) of copper powder (prepared from Reaction Eq. 18) and 791 mL of quinoline were added to a 1 L round bottomed flask and heated to reflux. Stirring was continued at 230 °C until complete release of carbon dioxide gas. After the reaction mixture was cooled to room temperature, the product was purified by column chromatography using hexane as eluent to finally obtain 58.8 g (75.4% yield) of the compound represented by formula 3-e.
