Successive Annulation to Fully Zigzag-Edged Polycyclic Heteroaromatic Hydrocarbons with Strong Blue–Green Electroluminescence
摘要:
A Bronsted-acid-promoted alkyne benzannulation approach was developed to synthesize the amino-substituted dibenze[a,j]anthracence derivatives in excellent yields, which were directly converted to fully zigzag-edged polycyclic heteroaromatic hydrocarbons via a nitrogen-directed electrophilic borylation. As the dopant in a blue-green electroluminescent device, the resulted compound exhibited relatively high stability.
