稀土酞菁化合物是一类新型的电致变色,气敏和有机半导体材料,因而长期以来引起人们的兴趣和注意. 合成稀土酞菁化合物的方法主要由等人提出用邻二氰基苯与乙酸稀土固相反应制得,产物经氧化铝柱色谱分离时得到蓝色和绿色两种物质,前者为夹层型稀土双酞菁化合物RE(C_(32)H_(16)N_8)_2·H,但关于绿色产物是否为单酞菁是长期争论的问题. 有关稀土单酞菁的合成曾有一些作者做了尝试,等人制出ErC_(32)H_(16)N_9·Cl·2H_2O和SmC_(32)H_(16)N_8·(HCO_2)两种化合物,Mackay制得ClC_(32)H_(16)N_8·YbCl·2H_2O.所有这些报道其元素分析结果与计算值相差较大,并未能确切证实是得到了纯的稀土单酞菁,Sugimoto虽报道过用稀土β-二酮盐与酞菁锂置换反应制得稀土单酞菁,但未见到详细的
Rare earth phthalocyanine compounds are a new class of electrochromic, gas-sensing and organic semiconducting materials and have long been of interest and attention. Methods for the synthesis of rare earth phthalocyanine compounds are mainly proposed by et al. Using ortho-dicyanobenzene with rare earth acetate Solid phase reaction, the product obtained by alumina column chromatography to obtain blue and green two substances, the former for the sandwich type rare earth bis phthalocyanine RE (C_ (32) H_ (16) N_8) _2 · H, but on Whether the green product is monophthalocyanine is a long-standing controversial issue.For the synthesis of rare earth monophthalocyanines, some attempts have been made to prepare ErC 32 H 16 N 9 Cl 2 2H 2 O and SmC 32, (16) N_8 · (HCO_2) and Clc_ (32) H_ (16) N_8 · YbCl · 2H_2O by Mackay, all of which reported a large difference between the elemental analysis and the calculated value and failed to confirm exactly Pure rare earth monophthalocyanine was obtained. Although Sugimoto reported that a rare earth monophthalocyanine was produced by displacement reaction of rare earth β-diketonate with lithium phthalocyanine, no detailed
