Phthalocyanine semiconductors

Despite the vast amount of reported OFETs with tetrapyrrole compounds as active semiconductors, the OFET performance of tetrapyrrole semiconductors is still very poor compared with the traditional inorganic semiconductors. On the basis of great potential applications of OFETs and the high theoretical charge transfer mobility of phthalocyanines, improving the OFET performance of existing phthalocyanine semiconductors and fabricating OFETs with novel phthalocyanine compounds will continue to draw the interests of scientists in future.
