 Abstract: Self-assembling monolayers (SAMs) of dithiols play an important role as bivalent linker layer in applications such as photoelectrochemical sensors. However, their formation processes and film structure are not fully understood yet. Herein, a SAM of aromatic trans-stilbenedithiol (StDT) on Au(111) surfaces is investigated. Using complementary characterization techniques the dependence of the film quality on preparation parameters, such as used solvent, temperature and ambient conditions during and subsequent to preparation is investigated. Furthermore, a remarkably high thermal stability is found which is ascribed to disulfide bridging between the endgroups of the individual molecules. © 2018 WILEY-VCH Verlag GmbH Co. KGaA, Weinheim
