This is an abstract for a presentation given at the
11th Foresight Conference on Molecular Nanotechnology


Self-limiting, layer-by-layer siloxane chemisorption offers the possibility of constructing, with nanoscale precision, robust, conformally adherent, optically functional, interlinked molecular assemblies composed of microstructurally and photophysically well-defined building blocks. We discuss here the implementation of such strategies for the fabrication and sub-µm patterning of organic electro-optic and emissive structures. In the electro-optic area, we report: i) efficient, automatable routes to very large electro-optic response self-assembled superlattices, ii) a new way to tune the refractive indices of such materials, iii) fabrication and properties of the first self-assembled electro-optic light modulators. In the light-emitting diode (OLED/PLED) area, we report: i) electrode passivation and charge injection balance control, ii) elucidation of matrix order vs. disorder effects on transport, iii) interfacial electrode-organic cohesion effects on injection efficiency and device robustness, iv) fabrication of functional nanodiodes having dimensions on the order of 40 nm, v) superior characteristics of new high-work function alternatives to ITO.
