Herein, we present a modular approach to pristine angularly fused planar acenes. The approach includes the Pd-catalyzed fusion of several building blocks and implements a dehydrative π-extension (DPEX) reaction as a key step enabling facile access to diverse two-dimensional acenes. The scope was demonstrated on nine examples with up to quantitative yield.
Towards nanographenes: Domino-DPEX (dehydrative π-extension) is a new synthetic approach to extended nanographenes containing a perylene or terrylene core. The pronounced regioselctivity towards aldehyde groups in different positions makes DPEX an excellent tool for implementing pre-programmed multiple annulation of simple precursors of elusive nanographenes. This approach enables the formation of

An organic light emitting device includes a substrate, an anode and a cathode disposed over the substrate, and a luminescent layer disposed between the anode and the cathode wherein the luminescent layer includes a host and at least one dopant. The host of the luminescent layer is selected to include a solid organic material comprising a mixture of at least two components, one of which contains at least one perylene carbocyclic ring structure or at least one mono-aza-perylene or poly-aza-perylene ring structure and is capable of forming both monomer state and an aggregate state.
