Abstract
Structures and methods that include selective electrostatic placement based on a dipole-to-dipole interaction of electron-rich carbon nanotubes onto an electron-deficient pre-patterned surface. The structure includes a substrate with a first surface having a first isoelectric point and at least one additional surface having a second isoelectric point. A self-assembled monolayer is selectively formed on the first surface and includes an electron deficient compound including a deprotonated pendant hydroxamic acid or a pendant phosphonic acid group or a pendant catechol group bound to the first surface. An organic solvent can be used to deposit the electron rich carbon nanotubes on the self-assembled monolayer.
