The small-mol. organic semiconductor tetraceno[2,3-b]thiophene was synthesized through an environmentally friendly synthetic route, using NaBH4, rather than Al/HgCl2, for the reduction of the quinone. Low-voltage organic thin-film transistors (TFTs) were fabricated using tetraceno[2,3-b]thiophene and, for comparison, pentacene and anthradithiophene as the semiconductor. The tetraceno[2,3-b]thiophene TFTs have an effective field-effect mobility as large as 0.55 cm2 V-1 s-1 and a subthreshold swing of 0.13 V/decade. The contact resistance of the tetraceno[2,3-b]thiophene TFTs is substantially smaller than that of the anthradithiophene TFTs and similar to that of the pentacene TFTs. The long-term air stability of TFTs based on all three semiconductors was monitored over a period of 12 mo. The initial charge-carrier mobility of the tetraceno[2,3-b]thiophene TFTs is ∼50% smaller than that of the pentacene TFTs, but as a result of the greater ionization potential and better air stability induced by the terminal thiophene ring condensed at the thiophene-b-bond, the tetraceno[2,3-b]thiophene TFTs outperform the pentacene TFTs after continuous exposure to ambient air for just 3 mo. In the experimental materials used by the author, we found 2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3Quality Control of 2-(Thiophen-3-yl)-1,3-dioxolane)
2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3) is one of dioxolane. 1,3-Dioxolane derivatives are recognized as important motifs for the construction of numerous pharmacologically active molecules as antiviral, antifungal, anti-HIV, and adrenoreceptor antagonists.Quality Control of 2-(Thiophen-3-yl)-1,3-dioxolane
