In this paper, we carried out the following works for the purpose of preparing the uniform micro (nano) structures that have a good performance of supermolecular: A variety of micron-sized C60 (C70) and H2TPP supermolecular structures have been prepared successfullly by liquid-liquid Interfacial precipitation (LLIP) method with five good solvents utilization of benzene, toluene, m-xylene, CCl4 and CS2 as solvent dissolving C60 (C70). According to the SEM of all kinds of micro (nano) structures of C60 (C70) and H2TPP, we have made a conclusion about the regularity of these structures as follows: compare with C60 and H2TPP supermolecular, C70 and H2TPP have a good hybrid nature and can form a uniform micro (nano) structures by self-organization easily. In benzene and IPA system, C70 and H2TPP supermolecular form C70-H2TPP nanorods, however, as to C60 and H2TPP supermolecular, quadrilateral C70-H2TPP nanosheets have been prepared. We have made a further research for two kinds of micro (nano) structures, a) In toluene and IPA, When C70:H2TPP=1:2, uniform quadrilateral C70-H2TPP nanosheets can be prepared . The effect of the ratio of C70 and H2TPP on the size and length of the C70-H2TPP microsheets have been studied, indicating that the length of C70-H2TPP microsheets can be readily controlled by adjusting the ratio of C70 and H2TPP. Raman spectroscopic characterization confirmed that C70-H2TPP microsheets are hybrid structures, the crystal structure of the C70-H2TPP microsheets has been investigated by XRD and TEM, an the data of XRD coincide with TEM.
