高次構造制御によるNLO色素の配向安定化を図った,新規でかつ非線形感受率の大きくかつ安定した2次のNLO特性を有するポリマーの分子設計に対する新しいアプローチとして,主鎖に対して垂直の方向に配向した遷移モーメントおよび双極子モーメントを有するNLO基を直接にポリマー骨格に固定した新規なポリマーを創製した。(この場合,主鎖中のベンゼン骨格はNLO色素の一部となる)。主鎖骨格には,剛直であるイミド結合(ポリイミド),全芳香族ポリアミド結合(アラミド)ならびに全芳香族ポリエステル結合(ポリアリレート)を導入して,それらのポリマーによるより高温で安定でかつ失活しない第2次高調波発振や電気光学変調等の光波マニピュレーションを行い,本年度研究の目的を達成した。ベンゾフェノンテトラカルボン酸を主鎖骨格に用いたNLOポリイミドでは,配向したNLO色素の緩和に対して100℃で50年以上また150℃では3.8年の緩和時間が得られ,このNLOポリイミドのNLO色素の配向安定性がより高温においても達成可能なことを示した。これは実用域に達するデータ(結果)である。さらに,イミド化の温度を上げると緩和時間は指数関数的に増加し,より配向安定性の向上が図れた。

The alignment of NLO pigments in high-order structural control is stable, and the new regulations are directly related to the non-linear sensitivity and stability of the second-order NLO properties. (In this case, in the main lock, there is a part of NLO pigment). The main structure of the system is composed of two parts: the first part is composed of three parts: the second part is composed of three parts: the first part is composed of three parts: the first part is composed of three parts: the second part is composed of three parts: the first part is composed of three parts: the first part is composed of three parts: the second part is composed of three parts: the first part is composed of three parts: the first part is composed of three parts: the second part is composed of three parts: the first part is composed of three parts: the first part is composed of three parts: the second part is composed of three parts: the first part is composed of four parts: the first part is composed of three parts: the first part is composed of four parts: the first part is composed of three parts: the first part is composed of four parts: the first part is composed of four parts: the second part is composed of four parts: the first part is The NLO pigment alignment stability is possible at 100℃ for more than 50 years and at 150℃ for 3.8 years. This is the result of the application. In addition, the temperature and relaxation time of the transition increase exponentially, and the alignment stability increases.
