The invention discloses an aromatic compound and application thereof. The structure of the aromatic compound is as shown in the following structural formula P: [A]-L-[B] formula P, wherein the structure of [A] is as shown in a formula 1, the structure of [B] is as shown in a formula 2, Y1-Y7 and Y8-Y12 respectively and independently represent N or CR1, and when the structure contains a plurality of CR1 groups, the CR1 groups are the same or different from each other; and when two adjacent groups of Y1-Y7, Y8-Y12 are represented as CR1, the adjacent CR1 may also form a monocyclic or polycyclic aliphatic, aromatic or heteroaromatic ring system with each other; l represents a divalent group, and Ra, Rb, R and R1, at each occurrence, are identical or different selected from the group consisting of H, D, F, aliphatic, aromatic and/or heteroaromatic hydrocarbon groups having 1 to 60 carbon atoms. According to the scheme, the problems of OLED product efficiency, service life, cost and the like ...
