合成了以不同链长的烷氧基柔性链相连接的金属铂(Ⅱ)-卟啉二聚体配合物并对其热稳定性,光谱性质及电化学性质做了研究。在浓度由10-7mol·dm-3增大到10-3mol·dm-3的过程中将配体与配合物的紫外-可见吸收光谱与光致发光光谱做了对比,发现配体与配合物的吸收光谱随浓度变化未出现改变,但发射光谱显现出随浓度增大而产生红移现象。当烷氧基柔性链中碳原子数大于4时,C6与C10配合物无论是高浓度下的溶液与升华固体薄膜中的荧光发射光谱均比配体有明显的红移,而短链的配合物无此性质。
Synthesis of metal platinum (Ⅱ) - porphyrin dimer complexes with different chain lengths of alkoxy flexible chains and their thermal stability, spectral properties and electrochemical properties were studied. In the concentration of 10-7mol · dm-3 increased to 10-3mol · dm-3 in the ligand and the complex UV-visible absorption spectra and photoluminescence spectra were compared and found that the ligand and the complex The absorption spectrum did not change with the concentration, but the emission spectrum showed red shift with increasing concentration. When the number of carbon atoms in the flexible chain of alkoxy is greater than 4, the fluorescence emission spectra of the C6 and C10 complexes both in the solution at high concentration and in the sublimation solid film have obvious red-shift compared with that of the ligand, No such property.
