Recent years have seen progress in several areas regarding single molecule electronic devices. A number of interesting structure–property relationships have been observed, including vibronic effects, spin transitions, and molecular electronic interference known as quantum interference. Together, these observations highlight what the rich opportunities in molecular design might bring in terms of advanced device properties. Pertinent challenges in the field of are related to development of high yield preparative procedures for fabrication of single molecule devices in a parallel and reproducible way. With this presentation we highlight our recent progress considering self-assembled formation of metal nanogaps incorporating single molecules for single molecule electronics applications. We discuss methods for the formation of the nanogaps as well as methods attempting to achieve single molecule functionality in each individual device. Examples include fabrication of single molecule devices by in-situ growth of gold nanorods, formation of nanogaps via deterministic self-assembly of gold nanorods, single molecule transport studies under influence of force pulling, a method for self-assembly of nanoparticle heterodimers, allowing for monitoring thermodynamics of hydrogen absorption on single particles designed molecules featuring quantum interference effects, as well as new approaches to control materials specific positioning of nanoparticles at surfaces
