摘要
本文介绍四种新的稀土（Ｎｄ，Ｐｒ）（Ⅲ）双酞菁衍生物合成：八－４－（四氢糖氧基）钕（Ⅲ）（Ａ）；八－４－（β－萘氧基）铁（Ⅲ）（Ｂ）；八－４－（２．４－二特戊基苯氧基）钕（Ⅲ）（Ｃ）；八－４－（２．４－二特戊基苯氧基）镨（Ⅲ）（Ｄ）．并通过元素分析、红外光谱、核磁共振谱加以确认。紫外可见光谱表明它们在氯仿（１０￣（１５）ｍｏＬ／Ｌ）溶液中以单分子形式存在，热重分析证明配合物的热稳定性：Ｂ＞Ｃ＞Ａ。实验得出，四种配合物成膜性好．
This paper introduces the synthesis of four different rare earth derivatives of diphthalocyanine:octa-4-(tetrahydro-saccharoxyl)neodymium(Ⅲ)(A):octa4-(β-naphthoxy)neodymium(Ⅲ)(B);octa4-(2,4-bis-(tert-pentyl)phenoxyl) neOdymium(Ⅲ)(C) and octa-4-(2,4-bis.(tert-pentyl)phenoxyl)praseodymium(Ⅲ)(D),which have been confirmed by elemental analysis,infrared spectrum(IR)and nuclear-magnetic re-sonant spectrum(NMR).Ultravionlet and visible spectrum(UV/Vis)proved that these four complexes exist asfree molecules in chlorOform solution(10-8mol/L).Thermal weight analysis showed that ths thermal stabilityof these comlexes:B>C>A, And the results indicate that the ability of film formation of these four complexesis good.
