Tb(Ⅲ)双酞菁配合物有序薄膜的制备及荧光特性

The Preparation of the Orderly Films of Tb(Ⅲ)-bisphthalocyanine Complexes and the Luminescence Properties

铽是典型的具有较强荧光特性的稀土元素。本文以铽的双酞菁配合物八 - 4 - (正壬氧基 )酞菁铽( )为原料 ,以 L B(L angmuir- Blodgett)单分子膜技术制备的酞菁铽多层 L B膜 ,以及其与花生酸按不同比例 (6∶ 4、5∶ 5和 4∶ 6 )混合的多层 L B膜。通过 π- A曲线、原子力显微镜、紫外可见光吸收光谱及荧光光谱等实验手段对它们的结构和荧光特性进行了表征。

Tb is an element of race earth with great fluorescence behavior.The Langmuir Blodgett (LB) films of Tb(Ⅲ) ocat 4 n nonyloxyphthalocyanine (TbPc) had been build up by the technology of LB films,as well as the blend LB films with TbPc and (AA) at the ratio of 6∶4,5∶5 and 4∶6 for TbPc:AA.By the π A isotherm,atomic force microscope (AFM),Uv vis absorption and fluorescence spectroscopy,the characteristic of their structure and fluorescence,in the range of visual light had been disclosed.The studies have shown the possibilities of the fabrication of molecule photo devices with LB films of TbPc.
