含金属钌配合物的可溶性三元聚酰亚胺的合成与表征

Synthesis and Characterization of Soluble Copolyimides Containing Ruthenium Complexes

通过改变与6FDA共缩聚的两种二胺单体的比例，在分子主链中引入具有庞大侧基的9，9-二苯基芴单元，然后和金属钌配合物进行配位，得到了三个含金属钌配合物的三元聚酰亚胺BFPI-1．Ru，BFPI-2-Ru和BFPI-3．Ru。用元素分析、GPC、FT—IR、TG和UV-Vis等对其分子量、结构及性质进行了表征。结果表明，随9，9-二苯基芴单元含量的增加，含金属聚合物在低沸点溶剂CHCl3和THF中的溶解性提高。所合成的含金属聚酰亚胺具有良好的热稳定性，在350～800nm较宽的紫外可见光区有良好的光吸收性质。

Three copolyimides containing ruthenium complexes （BFPI-Ru） were prepared by the copolymerization of 6FDA with two diamine monomers in different ratio and then by the complexation with a ruthenium complex. The Mw of the ligand polymers BFPI-1, BFPI-2 and BFPI-3 was measured by GPC. Their ruthenium complexes, BFPI- Ru, are soluble in common aprotic organic solvents Such as DMF. The solubility of BFPI-Ru in low boiling point solvents, such as chloroform and THF, increases with increasing the FBPA unit content. These copolyimides containing ruthenium complexes are thermaly stable as measured by TG analysis, and their DMF solution exhibits strong and broad absorptions in the visible spectrum region.
