摘要
由于可控的组分交换行为,动态酰腙键常被作为自排序和自修复智能材料的节点。平面四边形d~8结构的铂(Ⅱ)配合物趋向于自发形成有序的寡聚物,并发出强烈的~3MMLCT磷光。为获得光学性能可调的智能材料,我们将二者融入一个体系。动态酰腙键桥连的三支磺酸盐化合物和带正电的铂(Ⅱ)配合物通过静电吸引形成超分子聚合结构,并在水中产生强烈的~3MMLCT磷光。利用酸性条件下酰腙的水解和组分交换行为,我们获得了程序化的磷光发射~([1])。将动态共价键引入金属超分子体系的设计将有效拓展磷光输出可调软材料的开发思路。
Because of the controllable component exchanges, dynamic acylhydrazone bonds have been designed to act as self-sorting and self-healing knots in smart materials. Square-planar d~8 platinum(Ⅱ) complexes tend to arrange themselves into orderly oligomeric structures and show remarkable ~3MMLCT luminescence. In an effort to achieve tunable photophysical properties, both of them were meshed into a single system(Fig. 1). The electrostatic self-assembly of a tripodal dynamic acylhydrazone-bridged sulfonate with a cationic chloroplatinum(Ⅱ) complex leads to the formation of supramolecular aggregates and thus remarkable ~3MMLCT luminescence enhancement inaqueous solution. By virtue of hydrolysis and component exchange of the acylhydrazone bonds under acidic conditions, the ~3MMLCT emission was programmably controlled. The introduction of dynamic covalent bonds into metallo-supramolecular systems represents a new approach to develop luminescence soft materials with tunable optical outputs.
