Novel second-order nonlinear optical, aromatic, and aliphatic polyimides exhibiting high-temperature stability

摘要

Novel aromatic and aliphatic polyimides exhibiting sizable second-order nonlinear optical properties and long term thermal and temporal stability were synthesized. Detailed physical characterization revealed that the polymers are stable up to 300℃ with high glass transition temperatures (> 200℃). Exceptional thermal stabilities at elevated temperatures were observed even at 150℃.
