キノイド化合物（キノジメタン類、キノンメチド類、キノンメチドイミン類）を新規に合成し、それらの結晶構造解析と通して２回らせんの空間群の結晶を見出した。得られた結晶は反転中心を有するため熱、光固相重合により光学活性ポリマーは得られなかったが、２回らせん重合という新しい重合反応機構、選択的なシクロファン生成、固相重合反応における多様性を見出した。更に、固相重合反応により交互共重合体を得る有用な手法を提案した。
Novel quinoido-type compounds such as quinodimethanes, quinone methides, and quinone methide imines were synthesized and thier crystal structures were investigated by the single-crystal structure analysis. The crystals obtained belong to the space group of 21 helix axis involving inversion center. On the photochemical and thermal solid-state polymerizations, optically active polymers were not obtained. However, novel 21 helical polymerization mechanism, exclusive formation of paracyclophane, and the diversity in solid-state polymerizations were found. Moreover, novel method to obtain the alternating copolymer by solid-state polymerization was proposed.
