摘要：
Cyclization of 4-(2-halophenyl)-1H-pyrazolo[3,4-b] quinolines 3a-b and 9a-9b provided two regioisomeric compounds: 6-phenyl-6H-5,6,7-triazadibenzo[f,h] naphtho[3,2,1-cd] azulenes 4,10 and 1,3-diphenyl-3H-indeno[1,2,3-de]pyrazolo[ 3,4-b] quinolines 2,11. All of them are considered as new building blocks for optoelectronic materials. The two-step synthesis utilized readily available starting materials.
