The construction of coronenes using simple building blocks is a challenging task. In this work, triphenylene was used as a building block to construct functionalized coronenes, and their solid structures and optoelectronic properties were investigated. The single crystal structures showed that coronenes have different packing motifs. Their good solubility and photostability make them potential solution-processable candidates for organic devices.

Polycyclic aromatic hydrocarbons are of great interest as a result of their self-assembly properties and 5 excellent charge-transfer abilities. They are therefore promising candidates for organic semiconducting devices. In order to develop better optoelectronic devices, chemists have made considerable effort to investigate synthetic methods for polycyclic aromatic hydrocarbons. Among many building blocks, arynes are a promising reactive intermediate for the construction of polycyclic aromatic hydrocarbons and so has been studied over many decades. In this review, we will summarize recent progress on the 10 construction of polycyclic aromatic hydrocarbons using arynes as starting materials.

Imide-modified polycyclic aromatic hydrocarbons can be widely applied in the field of optoelectronic materials. In this work, we have synthesized four novel functionalized benzopicenes and characterized their solid structures and optoelectronic properties. The fluorescence of the four functionalized benzopicenes showed red shifts with increasing solvent polarity; the quantum yields are high in the solution state and moderate in the solid state. The single crystal structures show that the benzopicenes adopt a lamellar motif π-stacking. Their good solubility and optoelectronic properties make them potential solution-processable candidates for organic devices, bioimaging and biolabeling.
