Near infrared heptamethine cyanine dyes applied as functional dyes are gradually extending their application fields . the structure of the dyes and their synthesis and applications were reviewed with 23 references 近红处七甲川花菁染料作为功能染料不断得到广泛应用。本文主要对七甲川花菁染料的结构、合成及其应用进行了综述。参?文献23篇。
( 1 ) in chapter 5 , palladiumphthalocyanine and palladium 4 , 4 ' , 4 " , 4 ' " - tetranitrophthalo - cyanine were synthesized according to condensation method with high yield and high product purity . the structures of products were characterized by element analysis and ir spectra 为此，分别考察了不同引发剂及用量对pvp甲壳糖接枝共聚物的反应性能、接枝分子量、接枝效率以及产物的基本性状等的影响。
The method showed promising results compared with conventional methods . the second part : we mainly reported the synthesis of some chemical reagents such as palladiumphthalocyanine , palladium 4 , 4 ' , 4 " , 4 ' " - tetranitrophthalo - cyanine , pvp - chitosan grafting copolymer , n - propyl carboxylate , propionic esters （ 2 ）在第6章利用pvp优良的生物相容性，将其接枝到甲壳糖分子链，以改善甲壳糖作为组织工程材料应用的不足之处。
The gardenia green pigment is the yellow pigment which withdraws by the gardenia fruit water used , after the food processing with the enzyme processing production cyanine , but becomes again with the above yellow pigment mix , assumes the green powder , mainly uses in the common food coloration , stipulated according to japan , does not have to use in the kelp , the meats , the fresh fish shellfish , the tea , purple vegetable , the legumes and the vegetables 栀子绿色素是由栀子果实用水提取的黄色素，经食品加工用酶处理生成的蓝色素，再与上述黄色素混合而成，呈绿色粉末，主要用于一般食品的着色，按日本规定，不得用于海带、肉类、鲜鱼贝类、茶、紫菜类、豆类及蔬菜。
