What is 2,6-Dibromo-4,4-bis(2-ethylhexyl)-4H-cyclopenta[2,1-b:3,4-b']dithiophene?

Description

2,6-dibromo-4,4-bis(2-ethylhexyl)-4H-cyclopenta[1,2-b:5,4-b']dithiophene, with two thiophene units confined to one plane, cyclopenta[2,1-b;3,4-b′]dithiophene compounds allow?more effective conjugation if embedded into semiconducting polymers which in turn will have lowers the band gap. Furthermore, the planar structure will have greater effect on the morphology for the thin film devices to allow a well packed polymer?to polymer?backbones?which will bring the third-dimension into play. Take PCPDTBT for example, the planar structure improves the hole mobility of the device to 1 x 10-3 cm2/Vs.
