| Outline of Final Research Achievements |
In this study, novel gas permeable membrane materials for efficient gas separation of greenhouse gases were developed. It was found that the newly developed membrane based on consisting of heterocyclic compounds outperform conventional membranes, which are derivatives of pyrroles, thiophenes, furans, and their copolymers. The developed methods can directly access gas separation membranes with simultaneous polymerization and membrane fabrication in the presence of a strong acid catalyst. Although the gas permeability of these membrane materials is relatively low compared to conventional membrane materials, their gas separation performance is extremely high, and as a result, we have developed new materials that exceed Robeson's upper bound.

現在，地球規模で問題となっている温暖化現象の対策として温暖化ガスの回収は極めて重要である．本研究で開発した気体分離膜は混合ガスからの任意の期待の効率的分離を可能とするものであり，現在強く求められている技術の一つである．今回開発した新規の膜については温暖化ガスの一つである二酸化炭素の分離を当初の分離対象として膜材料を設計，開発してきたが二酸化炭素の分離能は従来のものと同等泥土となったが，その一方で窒素N2に対する酸素O2の分離能が極めて高いことが明らかとなった．当初の意図とは異なる結果ではあったが，結果は分離膜開発における分子設計指針を与える有意義なものであった．
