## Description

- description: 'Incorporating nitrogen into carbon-based materials can significantly
    modify their electronic properties. A comprehensive understanding of the structural
    and physical characteristics of aza-polycyclic aromatic hydrocarbons (aza-PAHs)
    is crucial for developing innovative materials. In this study, four aza-PAHs were
    synthesized using a combination of the Povarov reaction and intramolecular cyclization
    reaction via direct C–H arylation. The synthesized compounds were evaluated in
    terms of the crystal structure, photophysical properties, frontier energy levels,
    and hole-blocking properties in organic light-emitting diode (OLED). The intramolecular
    cyclization via direct C–H arylation afforded a condensed azaperylene molecule
    that exhibited long-wavelength absorption and emission, attributed to the high
    HOMO level resulting from π-extension. '
