有关氨基萘磺酸与金属离子生成的化合物的研究,文献曾有过报导,例如4—氨基萘磺酸钴是橡胶的组分和乙酰纤维素的稳定剂,镁盐可作为抗腐剂和聚胺纤维染料,铜盐作为尼龙的稳定剂和聚乙烯、聚丙烯中的核剂,钠盐有抗凝血作用等。而稀土离子与氨基萘磺酸的化合物的制备目前还没有报导过,因此开展这方面的研究是有意义的。近年发展起来的稀土生物化学是将稀土离子作为研究生物体系中碱土金属行为的探针,稀土与碱土金属离子的性质相似,当稀土与生物大分子化合物发生络合作用时,可以很方便地通过吸收光谱、萤光光谱以及顺磁性得到判断。氨基萘磺酸及其盐的溶液具有各样颜色萤光,例如2-氨基-6-萘磺酸呈微兰色萤光、2-氨基-7-萘磺酸呈红紫色萤光,2-氨基-8-萘磺酸具兰色萤光、1-氨基-5-萘磺酸具微绿色萤光等。因此合成出稳定的水溶性萤光化合物是有意义的,有可能在生物探针上寻找其新的应用。我们采用2-氨基-1-萘磺酸,1-氨基-5-萘磺酸和1-氨基-4-萘磺酸为原料,与各个稀土的氧化物或碳酸盐制备出稀土化合物34个,它们都具有萤光性质,并研究其红外光谱、电导、热谱、紫外吸收光谱和在各种溶剂中的溶解状况,这方面工作还没有人研究过。
Studies on the compounds produced by aminonaphthalene sulfonic acids and metal ions have been reported in the literature, for example, cobalt 4-aminonaphthalene sulfonate is a component of rubber and stabilizer of acetyl cellulose, and magnesium salts are useful as antiseptics and poly Amine fiber dyes, copper salt as a nylon stabilizer and polyethylene, nucleating agents in polypropylene, sodium anti-clotting effect and so on. The preparation of compounds of rare earth ions with aminonaphthalene sulfonic acid has not been reported yet, so it is significant to carry out this research. In recent years, the development of rare earth biochemistry is the rare earth ions as a probe of the behavior of alkaline earth metals in biological systems. The properties of rare earth and alkaline earth metal ions are similar. When rare earth complexes with biological macromolecules, they can be conveniently passed Absorption spectra, fluorescence spectra and paramagnetic properties are judged. A solution of aminonaphthalene sulfonic acid and its salt has fluorescent of various colors, for example, 2-amino-6-naphthalenesulfonic acid has a blue-orange fluorescence, 2-amino-7-naphthalenesulfonic acid has a purple-red fluorescence, Amino-8-naphthalene sulfonic acid with blue fluorescence, 1-amino-5-naphthalene sulfonic acid with greenish fluorescence and so on. Therefore, it is significant to synthesize stable water-soluble fluorescent compounds, and it is possible to find new applications in bio-probes. We used 2-amino-1-naphthalene sulfonic acid, 1-amino-5-naphthalene sulfonic acid and 1-amino-4-naphthalene sulfonic acid as raw materials, with the rare earth oxides or carbonates to prepare rare earth compounds 34 , All of which have fluorescent properties and have been studied for their work on infrared spectroscopy, conductance, thermometry, ultraviolet absorption spectroscopy and dissolution in various solvents.
