以聚芳醚砜为主链,金属酞菁作为接枝基团,分别合成了含有酞菁镁,酞菁锰,酞菁钴的聚芳醚砜。该类聚合物具有很好的热稳定性,其5%的分解温度均在360℃以上,在极性溶剂中展示出良好的溶解性能。对其光电性能进行表征,溶液的紫外-可见吸收均在300 nm～400 nm及600 nm～800 nm出现很强的光谱吸收,且吸收光谱的峰值随着中心金属原子的不同而出现不同程度的偏移。相对于溶液吸收光谱,固体的吸收光谱出现一定程度的红移。结果显示,这类物质具有优异的光吸收特性,在光电领域具有一定的应用前景。
A series of poly（arylene ether sulfone）s with metallophthalocyanine as grafted group were successfully synthesized.The synthesized copolymers exhibit good thermostability.The 5% mass loss temperatures of these polymers are all above 360 ℃.These polymers also show a good solubility in polar solvents.The UV-vis absorption and photoluminescence spectra were characterized.These colored polymers show visible absorption in the range of 300 nm～800 nm and exist a shift with different metal atoms.Compared with solution absorption spectra,the solid film absorption spectra of these polymers appear a red shift.All the properties show the polymers have a potential application in photovoltaic field.
