In the last two decades, organic π-conjugated materials have attracted immense interest due to their versatility in tuning optical and electronic properties, as promising candidates for various opto-electronic applications, such as organic light emitting diodes (OLEDs), field effect transistors, solar cells and photodetectors.^1–4  While the majority of such materials have initially been based on the polymers due to their easy processability and affordable mechanical properties, their ill-defined and complicated structures and morphologies have seriously limited a clear understanding of their inherent properties, which has hindered exploitation of the full potential of π-conjugated materials by demanding tedious protocols for device optimization. Thus, the focus has been gradually shifted to small organic molecules and oligomers, which benefit from a well-defined chemical structure and precisely tunable intra- and intermolecular interactions, toward active components for organic sensors, field effect transistors, solar cells, light-emitting diodes and lasers.⁵
