• Three types of solid-state 31P-nuclear magnetic resonance (NMR) analysis, namely, cross polarization and magic angle spinning (CP MAS), pulse saturation transfer and magic angle spinning (PST MAS), and gated high power decoupling and magic angle spinning (HPDEC MAS) analyses were performed on a fluorinated polymer containing Eu(III) complexes with two types of phosphine oxide. Spectra were dependent on the pulse sequence of NMR. In PST MAS and HPDEC MAS analyses, two sharp signals corresponding to two phosphine oxides coordinated with one Eu(III) ion were identified. On the other hand, in CP MAS analysis, no clear signal was detected. The difference in the spectra suggests that coordinated phosphine oxides exist mainly in the amorphous parts, not in the crystallized parts of matrix polymers.
