• 論文の詳細を見る

• A new crown ether spin-labeled by the phenoxyl radical moiety was prepared. Intramolecular odd-π electron delocalization was investigated by means of ENDOR spectroscopy. On the basis of ENDOR spectrometric titration, the equilibrium constant for Na<SUP>+</SUP>-labeled crown-ether-complex formation was evaluated to be p<I>K</I><SUB>Na</SUB><SUP>+</SUP>=3.5 in 2-propanol at −30 °C.
