| 摘 要： | 研究了从Sm^3^+到Lu^3^+(Gd^3^+除外)九个稀土单酞菁化合物的^1H NMR化学位移.发现对重稀土化合物,酞菁环上α、β质子诱导位移符号的变化呈现"三个一组效应".即,"Tb^3^+、Dy^3^+、Ho^3^+化合物,^1H共振谱线移向高场,而对Er^3^+、Tm^+^3、Yb^3^+化合物,则移向低场.化学位移的最大变化发生在4f^8构型(Tb^3^+)处.所得结果与Bleaney理论一致.测得部分稀土单酞菁化合物的^1^3C NMR谱,讨论了化学位移的变化.

| Abstract: | The variations of the 1H NMR chem. shifts of the monophthalocyaninatolanthanide(III) compounds for 9 rare earth elements from Sm3+ to Lu3+ (except Gd3+) were studied. A "triad effect" appears in the sign alternation of the induced chem. shifts of the a, b-protons in the phthalocyanine rings for the 2nd half of the rare earth series. That is 1H NMR spectra are shifted upfield for Tb3+, Dy3+, and Ho3+ compounds and shifted downfield for Er3+ Tm3+, and Yb3+ compounds The largest alternation of the chem. shifts appears in the Tb3+ compound This is inconsistent with the regularity obtained theor. by B. Bleaney (1972) for the whole rare earth series. The 13O NMR spectra of several monophthalocyaninatolanthanide compounds are described and the variations of the chem. shifts discussed. |
