Cycloalkylalkylphosphonic acids are presented that are useful for forming a self-assembled monolayer (SAM) on a surface of a metal oxide layer. The combined SAM and metal oxide layer form the dielectric layer of an organic thin film transistor (OTFT). The OTFT can be formed with p-type and n-type organic semiconductor layers on the SAM. The OTFT display superior field effect mobilities and air stabilities to other SAMs and the SAMS of cycloalkylalkylphosphonic acids allow deposition of the organic semiconductors by either vapor deposition or solution processing techniques.
