两类四氨基酞菁的合成及其性质研究

分别由4-硝基邻苯二甲酰亚胺、3-硝基邻苯二甲酸酐和金属盐、尿素、钼酸铵在熔融状态下合成2,9,16,23-四-硝基金属酞菁、1,8,15,22-四-硝基金属酞菁,还原得到两类四氨基金属酞菁.用红外光谱、紫外-可见光谱对目标化合物进行了表征,并对金属酞菁的电导率进行了测定.结果表明:在紫外吸收光谱中,Co,Cu,Ni和Zn 4种金属对氨基取代酞菁化合物最大吸收波长的影响顺序大致相同.8种酞菁化合物的电导率随着温度的升高均有不同程度的增大.对于金属Co,Cu和Ni取代的酞菁化合物来说,1,8,15,22-四-氨基取代酞菁化合物均比2,9,16,23-四-氨基取代酞菁化合物的电导率大,而Zn则相反.

Studies on synthesis and properties of two kinds of the tetraaminophthalocyanine

The (NO_2)_4PcM(Ⅱ) (NO_2 groups in 2,9,16,23 position) and (NO_2)_4PcM(Ⅱ) (NO_2 groups in 1,8,15,22 position) (metal contain Co,Ni,Cu,Zn) were prepared by 4-nitrophthalimide,3-nitrophthalic anhydride respective react with metal salts,urea and ammonium molybdate in molten state,then two kinds of tetraaminophthalocyanine were obtained by reducing reaction,and the products were charactered by IR spectra and UV-vis electronic absorption spectra,conductivity of different kinds of metal substitute aminophthalocyanine were obtained.The results showed similar influencing results of the greatest absorption wave length of four metals contained by the phthalocyanine substituted with NH_2 groups in different position were Ni＞Cu＞Zn＞Co were found.With the increasing of temperature,the conductivity of eight kinds of phthalocyanine compounds were increased.For the Co,Ni,Cu substituted of the phthalocyanine,the conductivity of tetraaminophthalocyanine (NH_2 groups in 1,8,15,22 position) was bigger than tetraaminophthalocyanine (NH_2 groups in 2,9,16,23 position),excepting Zn.
