Although organic semiconductors with high mobility and thermal stability are particularly desirable for practical applications, facile methods for their development still remains a big challenge. In this work, a charge-transfer cocrystal based on fullerene (C70)/cobalt porphyrin supramolecular architecture was prepared by a solution-processable co-assembly strategy. This supramolecular architecture showed hole mobility as high as 4.21 cm2·V-1·s-1, and a relatively high mobility of 0.02 cm2·V-1·s-1 even after thermal treatment at 1,000 ℃. Further studies confirmed the occurrence of charge-transfer from 5,10,15,20- tetrakis(4-methoxyphenyl)porphyrinato cobalt(II) (CoTMPP) to Czo and the paramagnetic character within the supramolecular system. These factors were found to be responsible for the aforementioned superior performances. Thus, a novel organic semiconductor has been reported in this work, which can be potentially used for next generation electronic devices. Furthermore, it has been demonstrated that charge-transfer co-crystallization is a powerful strategy for the rational design and construction of a broad class of new multifunctional organic co-crystalline materials.
