Synthesis of Conjugated Tris- and Tetrakis (Carbazolyl) Azulenes with Intense Emission in the Visible Range
{{output}}
New conjugated carbazolyl-substituted azulenes, such as 1,2,3-tris(carbazolyl)azulene and 1,2,3,6-tetrakis(carbazolyl)azulene, were synthesized via cross-coupling reactions in high yields. The resulting compounds exhibit a significant ability to absorb and emi... ...
