The Synthesis and Characterization of PANI - CuPc Organic Semiconductor Hybrid Material

Abstract

CuPc was synthesized with 4-Nitrophthalonitrile and p-Cresol as the source materials of benzene ring by the template synthesis method of two steps reaction. With aniline as the source material of polyaniline, using chemical oxidative polymerization method of one-step reaction, through doping with perchloric acid, vitriol and nitric acid obtained semiconducting doped PANI. On this basis, selected the intermediate substance of reactive process, by means of molecular hybrid modification polymerized the two substances to form a kind of new organic semiconductor material CuPcxPANI1-x. Through the analysis of characterization means such as mass-spectrometry, infrared absorption spectroscopyand thermogravimetry, the results indicated that molecular weight of the phthalocyanin molecular fragment was confirmed as 234 through the analysis of mass-spectrometry, and the theoretical value of phthalocyanin was 234.34, which validated that the synthesis process of the phthalocyanin molecular fragment was right. Through the analysis of thermogravimetry, the new substance from hybrid synthesis forming thin film was viable using the technology of evaporation.
