Sažetak
Compounds with multiple aromatic nitroso groups can interact to form polymeric azodioxides. The simplest such compound is 1, 4-dinitrosobenzene which polymerizes into a very stable one- dimensional (1D) polymer, classified as a potential wide-bandgap organic semiconductor [1]. The polymerization property of aromatic dinitroso compounds could be used to design azodioxy thin films on metal surfaces. We investigated the polymerization of various aromatic dinitroso compounds initiated by nitroso- terminated monolayer on Au(111) surface [2] by ellipsometry, atomic force microscopy (AFM) and nano-FTIR spectroscopy. The obtained results indicated the formation of azodioxy oligomer films and a greater tendency towards oligomerization with a longer adsorption time [3]. In addition to providing important new insights into surface-initiated interactions of aromatic C- nitroso compounds, this study also demonstrated the high sensitivity of nano-FTIR spectroscopy for the chemical identification of very thin films (Figure 1).
