摘要 (Abstract) |
|
| The Patent primarily adopts molecular design and Chichibabin reaction to synthesize novel pyridine heterocyclic compounds consisting of carbazole, pyrene, or reactive bromine functional groups and fabricate a series of pyridine heterocyclic-containing heat-resistant polymers through polycondensation polymerization technologies. Suzuki coupling technique is used in the modification to introduce naphthalene, pyrene, fluorene, and carbazole functional groups to a series of reactive bromine-containi | |
