Bis(triisopropylsilylethynyl)-substituted pyrene-fused tetraazaheptacene: synthesis and properties

The synthesis and characterisation of a pyrene-fused tetraazaheptacene that is constituted of two terminal pyrene units and a central tetraazaanthracene core are reported. The optoelectronic properties (experimental and calculated) of this heptacene derivative are discussed together with its charge transport properties in thin films.
