摘要：
Add an O: A new strategy for preparing solution-processed organic thin-film transistors (OTFTs) is based on enhancing the surface energy of self-assembled monolayers (SAMs) by inserting polar oxygen atoms into the long alkyl chain of phosphonic acids. SAMs of these phosphonic acids on a high-k metal oxide layer lead to solution-processed n-channel OTFTs with average field effect mobilities of up to 2.5 cm2 V-1 s-1 and low operational voltages.
