Description
Technical Field
The invention belongs to the field of functional materials, and relates to a one-dimensional cyano-bridge binuclear metal organic compound, and a preparation method and application thereof.
Background
In recent years, coordination polymers as novel functional materials have attracted the interest of researchers due to the interesting network topology and ideal functionalized structure, and among them, metal complexes with fluorescent properties have been studied in one of the hot spots. Ruthenium (II) complexes containing polypyridine ligands have been extensively studied for their spectroscopic, photophysical, photochemical and electrochemical properties. The advantage of such complexes is that they can absorb light in the visible region, produce metal-to-ligand charge transfer (MLCT) excited states, or undergo very fast intersystem crossing to give potentially long lifetimes3MLCT excited state. The ruthenium (II) polypyridine complex is in an octahedral configuration, can be used as a host molecule to well control the space volume around a ligand and the interaction with other guest molecules, has a great plasticity in a molecular structure, and can be used for designing a variety of molecular devices with different functions by changing the ligand or modifying the ligand. The complex plays an important role in the fields of green plant optical system simulation, pH luminous sensing, anion recognition, metal ion recognition, DNA molecule recognition and the like. Tridentate terpyridine (tpy) type chelating unitThe adjustability and the construction of linear rod-like structures are often used for designing and synthesizing photosensitive polypyridine (II) complexes. In addition to tpy itself, a large number of tridentate terpyridine ligands with different functionalities have been designed by varying the steric hindrance, electronic effects and photophysical properties of the complex.
The fluorescence properties of the metal complex, including the emission intensity and the emission wavelength of fluorescence, are not only related to the central metal ion, but also have a great relationship with the molecular structure of the organic ligand. The invention selects cyanide as an organic ligand, mainly because cyanide bridge is a good electron carrier, can effectively transfer intramolecular electron transfer, shows abundant electron transfer behaviors, and can emit stronger fluorescence. In addition, the cyano group can form structures with various configurations such as zero dimension, one dimension, two dimensions, three dimensions and the like by metal ions
The spectral properties can generally be adjusted by varying the different organic ligands and/or introducing ligands into the ruthenium (II) complexes containing polypyridyl ligands. It is worth mentioning that the cyanogen bridge polynuclear compound greatly promotes the development of the cyanogen bridge polynuclear compound in the field of luminescent materials due to the superiorities of relatively simple synthesis, controllable structure and the like compared with other polynuclear compounds.
