同多和杂多阴离子的有机衍生物是一类新型的催化剂,并可用作电子显微镜的染色剂,还可标记有机化合物的特殊官能团或大分子的生物活性部分。自1975年以来,对它的研究已成为多酸化学中极其活跃的领域叫。由于有机配位体纷繁多样,十余年来,合成的新化合物层出不穷。至今已制备出原子数超过500的单一分子和分子量约为10~6的高分子聚合物。近几年 Organic derivatives of isopoly and heteropolyanions are a new class of catalysts that can be used as electron microscopy stains as well as to label specific functional groups of organic compounds or bioactive parts of macromolecules. Research on it has become an extremely active area in polyacid chemistry since 1975. Due to the diversity of organic ligands, more than ten years, new compounds synthesized one after another. To date, single molecules with a number of atoms exceeding 500 and high molecular weight polymers having a molecular weight of about 10 to 6 have been prepared. recent years
