[Abstract] Fused, ladder-type organic materials have inherent advantages, such as extended Pi-frameworks, favorable stacking behavior in the solid state, conductivity, and high field-effect mobility. We have reported a wide range of quinoxalinophenanthrophenazine (TQPP) compounds. The introduction of nitrogen atoms in the TQPP core decreases the HOMO-LUMO gap, making the compounds of more interest in electronic applications. Besides, the planarity of the core in the TQPP compounds facilitates the efficient cofacial stacking of the materials in the solid state and increases the intermolecular Pi-orbital overlap. Combining the electronic properties of the electron-deficient TQPP chromophore with the predisposition of the TQPP compounds to self-organize into efficient self-assembled Pi-Pi columnar stacks in a single molecule offers an interesting combination of physical properties and, perhaps, a route to new materials for electronic applications. In this talk, we will discuss the different properties and features of the TQPP compounds.
