Synthesis and study the properties of novel heat resistant and luminescent polyamides having quinoxaline and carbazole groups in their backbone

High performance thermoplastic polyamides as a class of heat resistant materials have increasing demand particularly in the aerospace and microelectronic industries owing to theirdesirable characteristics including high thermal oxidative and hydrolytic stability, moderately high glass transitiontemperature, good solubility in selected organic solvents, good dimensional stability, low dielectric constant and tough mechanical properties [1,2]. Generally, the incorporation ofaromatic heterocyclic rings into the macromolecular chain remarkably improves the thermal stability of polymers andwill target applications including dielectric films, interlayer dielectrics, or passivation coatings in integrated circuits. Quinoxaline as a heterocyclic compound has aroused special interests in recent years due to its high electron affinity and good thermal stability [3,4].
