Self-organization of organic molecules is ubiquitous in nature, and also considered a promising route towards technologically relevant materials. In this lecture the deposition and interfacial self-organization of various types of organic molecules is studied in UHV, in solution and in air. The characterization of the resultant structures is done in situ, i.e. within the respective environment, using mainly scanning probe techniques (STM, AFM), complemented by spectroscopic methods like XPS, XPD, and IRRAS. Specific examples include the adsorption of phthalocyanine molecules on a Au(110) surface in UHV, the deposition of viologene and porphyrine molecules on anion-modified copper single crystal electrode surfaces, as well as the self-assembly of lang-chain aliphatic alcohole ('wax' -) molecules from Lotus leaves. Besides an understanding of the various systems this lecture aimes at an extension of the so-called 'surface science approach' to other ambients than UHV.
