摘　　要：Two novel boron(B),sulfur(S),nitrogen(N)-doped polycyclic aromatic hydrocarbon multiple resonance emitters(DBNS and DBNS-tBu)are designed and synthesized for narrowband red emission by embedding two pairs of S and N atoms and two B atoms in para-positions of central benzene rings within a tridecacyclic aromatic skeleton to form donor-π-donor(D-π-D)and acceptor-π-acceptor(A-π-A)structures,which not only exhibit emission maximum at 641 nm with small full width at half maximum of 39 nm,but also combine high photoluminescent quantum efficiency(85%)and rapid reverse intersystem crossing(kRISC=2.2×10^(5) s^(−1)).
