通过逐步聚合的方法合成了一种新的含有长烷基链的金属酞菁的聚合物,这种自组装的聚合物有很好的溶解性能,且很容易成膜,并对其光以及电化学性能进行研究.从紫外可见光谱图中可以看到两个强的吸收带,分别位于600-700 nm,以及300-400 nm.这种物质具有低的禁带宽度(Eg<1.8 eV),很容易吸收太阳光.采用332 nm的光作为激发光源,它的溶液的发射峰出现在402nm.从循环伏安图上可以观察到,两个可逆的氧化还原过程出现在0.64 V,-1.10 V.

A novel magnesium phthalecyanine (MgPc) polymer with long alkyl main chain was synthesized by step-growth polymeriza-tion. This serf-assembly polymer was found to have good solubility and be capable of forming films. The optical and electrochemical properties of the colored polymer were evaluated. The absorption measurements in the UV-vis region showed two intense absorption bands at the range of 600 -700 nm and 300 -400 nm. The low band gap polymer (Eg < 1.8 eV which was estimated from the ab-sorption onset) was an alternative for better harvesting of the solar spectrum. By employing 332 nm as the excitation light, the emission peak of this polymer in dimethyl acetamide was observed at402 nm. The results of cyclic voltammetry (CV) of the MgPc polymer were also reported showing reversible redox processes at 0.64 V and-1.10 V.
