  • Descrição: Self‐assembled monolayers (SAMs), combined with the lithography, were employed to fabricate functional surfaces. A new strategy in SAM technology, by using reiterated micro contact printing process, was proposed to produce a multi‐level fluorescent TAG (multi‐TAG), which consists of two overlapping micrometric patterns, made of a fluorescent oligothiophene SAM bonded with a Si/3‐aminopropylthriethoxysilane substrate. The samples were characterized by fluorescence microscopy, X‐ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES). In particular, the process of chemical interaction occurring during the self‐assembling was investigated. The obtained results showed that the SAM process occurred with the amidic bond formation. Moreover, the grazing‐angle XPS measurements indicated that the horizontal arrangement of oligothiophene molecules on the substrate surface was preferred. Copyright © 2016 John Wiley & Sons, Ltd.
