For the PEO-grafted polyaniline series with different contents of EO units, the benzenoid absorption peaks exhibited blue shifts in comparison with polyaniline, the shifts became greater as the content of EO units increased.

与聚苯胺相比，在共聚物的UV-Vis吸收光谱中，原来320nm处的苯环吸收峰出现了蓝移，其蓝移程度随着共聚物EO单元含量的增大而加剧，且Poly较Poly发生更大的蓝移。

The polymeric copper tetraaminophthalocyanine incorporated with aniline film (p-CuTAPc-PAN) was prepared using electrogeneration. The polymeric reaction between CuTAPc and aniline occurs as a result of the attack of an electrophile such as the cation radical NH2 groups remaining the p-CuTAPc on the 2-positon of the benzenoid ring.
