复杂有机膦酸盐的结构与性能

Complicated phosphonates have a broad prospect of application in the field of high technology advanced materials, like chemical sensor and molecular probe. Special organism (including pyrene, anthracene, naphthalene,benzene, biphenyl, azo, styrene, quinoline, triazine) will be modified with -PO3H2 group along with amino acid, pyridine and COOH groups, resulting in many new phosphonic acids with good water-solubility and coordination capability. Hydrothermal and solvothermal reactions of such new phosphonic acids with Zn, Mn, Eu, Tb and so on, will afford a series of new complicated phosphonates and explore structural rules. Thermal stability, magnetism, adsorption, second-order nonlinear optical,luminescence, luminescent sensitivity and so on, will be systematically studied. Furthermore, the relationship of these properties between structures will be also studied. We hope that some crystals of complicated phosphonates with excellent properties will be obtained.
