Description

2,6-Bis{5-fluoro-7-(5'-hexyl-2,2'-bithiophen-5-yl) benzo[c ][1,2,5]thiadiazol-4-yl}-(4,4'-bis(2-ethylhexyl) dithieno[3,2-b :2',3'-d ]silole, also named DTS (FBTTh₂)₂, is a non-polymeric electron donor. As a small molecule donor material, it has monodispersity and higher crystallinity than polymer donor materials. The study found that DTS (FBTTh2)2 was about twice as stable as Poly (3-hexylthiophene) and that heating annealing at 180°C for 20 min increased its stability by three times.
