酞菁铜磺酰氯接枝聚苯胺的合成与表征

Synthesis of Polyaniline Grafted by Cu Chloric Sulfonic Acid Phthalocyanine

以酞菁铜和氯磺酸为原料合成出氯磺化酞菁铜，用其对本征态聚苯胺进行接枝聚合，获得了侧链具有酞菁功能基分子结构的聚苯胺．该聚合物具有优良的溶解性能和成膜能力，电导率达到１０ － １ Ｓ／ｃｍ ，利用红外谱图证实了所合成产物的结构．紫外吸收分析表明，用酞菁铜磺酰氯接枝聚苯胺后，其在可见光区、近红外区都具有较强的吸收，极可能会大幅度地提高其光电导性能．热失重研究也表明了聚苯胺用酞菁铜磺酰氯接枝后，热稳定性较原来提高了１００ ℃。

Using Cu phthalocyanine and chloric sulfonic acid as raw material, Cu chloric sulfonic acid phthalocyanine (Cu CSAPc) is examined. Molecular structure of the polyaniline contained CuPc functional group is synthesized from Cu CSAPc and intrinsic polyaniline. Obtained is the photoconductive polymer polyaniline containing phthalocyanine. The polymer has high solubility and fine ability to film. The conductivity reached 10 -1 S/cm. IR identifies the designed chemical structure of the polymer. The absorption of polyaniline grafted with Cu CSAPc is very intense in the range of visible light and near infrared (i.e., the UV vis spectrum). The photoconductivity of the polymer is greatly enhanced. TGA shows that thermo stability of the synthesized polymer is greatly enhanced about 100 ℃. It can be seen from transition electron microscope that the crystallinity of the polymer is obviously improved.
