Polycyclic aromatic hydrocarbons (PAHs) are of great potential in molecular materials for opto-electronic devices. Their bandgap and supramolecular organization is tunable through modification of the p-system and lateral aliphatic substituents. An alternative original approach uses the versatility of heterochemistry with the successfull incorporation of N, O, S or B within the p-conjugated framework of PAHs.[1] Here, we report that this strategy can be extended to P-modified PAHs.[2] A synthetic route to a family of P-modified PAHs is described and their physical properties are described. Furthermore, the P-containing PAHs can be used as building block for the develepment of new PAH’ structures which are not accessible by other methods.
