摘要:
Disclosed is a process for purifying monomers of Formula (II): wherein R1 and R2 are independently selected from alkyl, substituted alkyl, aryl, substituted aryl, alkoxy, substituted alkoxy, and halogen; and R′ is selected from hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, alkoxy, substituted alkoxy, and halogen. After the monomer is synthesized, it is purified by column chromatography using neutral alumina and hexane as an eluent. The resulting product can also be further recrystallized using isopropanol, hexane, heptane, or toluene. Polymers formed from the purified monomer exhibit higher mobility and increased reproducibility of the mobility.
摘要:
Organic thin film transistors with improved mobility are disclosed. The semiconducting layer comprises a semiconductor material of Formula (I): wherein R1 and R2 are independently selected from alkyl, substituted alkyl, aryl, and substituted aryl; and R3 and R4 are independently selected from hydrogen, alkyl, substituted alkyl, aryl, and substituted aryl. A silanized interfacial layer is also present which has alkyl sidechains extending from its surface towards the semiconducting layer.

摘要:
Disclosed are semiconducting polythiophenes comprising a repeating unit of Formula (A) or a copolythiophene of Formula (B): wherein A and B are each alkyl having from 1 to about 25 carbon atoms; and a, b, c, d, e, f, g, x, and y are as defined herein. These polythiophenes have high mobility and are soluble in common organic solvents, so that chlorinated solvents do not need to be used. They are useful for depositing semiconducting layers, particularly in organic thin-film transistors.
