Terthiophene is the organic compound with the formula [C4H3S]2C4H2S. In the most common isomer, two thiophene rings are connected via their 2 positions to a central thiophene, also at the carbon atoms flanking the sulfur. This isomer is a pigment in marigolds and exhibits some biological activity upon photo-activation. Terthiophenes have been employed as building blocks for the organic semi-conductor polythiophene.
