Description
Summary:The cover shows a schematic of scanning probe nanolithography based on the spatial confinement of an oxidation reaction within a water meniscus, and its application for fabricating ordered arrays of cationic Mn12 single‐molecule magnets. Romero, Coronado, Garcìa, and co‐workers report on p. 291 that electrostatic interactions between the molecules and trapped charges within the nanodots drive the positioning of the molecules at the nanoscale. Manipulation of molecules with nanoscale accuracy is important in nanotechnology. In the novel process reported here, electrostatic interactions direct the deposition of polycationic Mn12 single‐molecule magnets into a predefined region of a 1 cm2 silicon chip with 40 nm accuracy (see figure). The process is based on the integration of local oxidation nanolithography with surface functionalization of the Si substrate.
