The invention provides a linear aza-polycyclic aromatic hydrocarbon compound as well as a preparation method and application thereof, and relates to the technical field of organic electroluminescent materials. According to the compound provided by the invention, a plurality of N atoms (greater than or equal to 4) are introduced into proper positions in a linear acene skeleton (the number of condensed rings is greater than or equal to 5), and localized and staggered front line orbit distribution is generated by virtue of electronegativity difference synergistic induction of the C and N atoms, namely HOMO / LUMO orbits are localized and are alternately distributed on a single atom or an isolated double bond; and the transition ratio of the bond formation / anti-bond orbit is effectively inhibited. The number of condensed rings of a linear acene skeleton is limited to be larger than or equal to 5, so that the horizontal orientation rate of molecules is improved, higher optical coupling output of luminescent molecules in a device is promoted, more importantly, bond length averaging is achieved, stretching vibration in the transition process is greatly restrained, and the molecular rigidity is improved; the emission spectrum (FWHM is narrowed to 10-20 nm) is narrowed, and meanwhile, the high fluorescence quantum yield (PLQY can reach 90% or above) is achieved.
