New non-symmetrical azobenzene derivatives have been synthesized as potential molecular electronic switching device candidates. The Oxone 0 mediated oxidation of anilines provided nitroso-functionalized arenes, which were then condensed with substituted anilines to provide a series of azobenzene derivatives that could be further converted into oligo(phenylene ethynylene)s or diazonium salts. The resulting thiolacetates, thiols, or diazonium salts are capable of forming molecular layers on the surface of gold or silicon, thereby paving the way for molecular electronics testing.

Various triazatriangulenes are synthesized by nucleophilic attack at the central C atom of triazatriangulenium ions. The molecular functions, especially azobenzenes, are fixed via an ethynyl linker by in situ deprotection of trimethylsilyl-alkynes. The structure of two of these molecules is further investigated by X-ray crystallography. The photo-induced trans/cis-isomerization of the azobenzene substituted
