WebMar 1, 2024 · Thiophene-based compounds are considered as favorable small molecular p-channel organic semiconductor [10], [11], [12]. Notably, distinguishing features of thiophene are sulfur atom and five-membered heteroaromatic compound with six π electrons (4n+2) [13]. Since sulfur atom possesses 3d orbitals, it has high polarizability [14].
