In this work, we report on the design, synthesis, thin-film growth, and optoelectronic properties of the newly synthesized dithienothiophene derivative 2,6-bis-(5?-hexyl-[2,2?]bithiophen- 5-yl)-3,5-dimethyl-dithieno[3,2-b;2?,3?-d]thiophene (DTT7Me). DTT7Me films, grown both by vacuum sublimation and, more importantly for technological applications, by drop casting, were successfully employed as active layers in Organic Light Emitting Transistors (OLETs).

Abstract
In this work, we report on the design, synthesis, thin-film growth, and optoelectronic properties of the newly synthesized dithienothiophene derivative 2,6-bis-(5?-hexyl-[2,2?]bithiophen- 5-yl)-3,5-dimethyl-dithieno[3,2-b;2?,3?-d]thiophene (DTT7Me). DTT7Me films, grown both by vacuum sublimation and, more importantly for technological applications, by drop casting, were successfully employed as active layers in Organic Light Emitting Transistors (OLETs).File in questo prodotto:
