Self-Assembled Monolayers of a Multifunctional Organic Radical

摘要

The ultimate goal of molecular bottom-up approaches is to employ functional building blocks to construct nanometer-scale devices that address specific applications. Furthermore, immobilization of functional molecules on suitable surfaces is also often required for implementation of a practical device. One powerful and versatile strategy for the modification of surfaces at the molecular level is by the preparation of self-assembled monolayers (SAMs). Although most attention has focused on SAMs of thiols on gold, the use of glass, quartz, or silicon (namely, SiO2) substrates offers clear advantages for preparing SAMs since these systems exhibit superior stability, are compatible with established silicon technologies, and allow the use of optical techniques as read-out mechanisms.
