Temperature dependence of C60 solubility in four organic solvents above room temperature was investigated. It is found that the solubilities decrease with increase in temperature in hexane, toluene and xylene while it...Temperature dependence of C60 solubility in four organic solvents above room temperature was investigated. It is found that the solubilities decrease with increase in temperature in hexane, toluene and xylene while it increases in cyclohexane. Least square fit gives the heat of solution of C60 in hexane,toluene, xylene and cyclohexane as -6.0, -9.8. -9. 1 and 48.2 KJ/mol respectively.展开更多

The results show that C60 doping can remarkably enhance the photoconductivity compared with the corresponding pure materials. The X-ray powder diffraction pattern and lR spectrum suggest that the enhancement of photoconductivity may be due to the polymorphic transformation and the change of molecular interaction in phthalocyanine composites. and a chargetransfer complex (CTC) of ZnPc with C60 may be formed.展开更多

Compared with pure PEPC, fullerenated PEPC has the same structure in the UV region of the absorption spectrum, and extends the active range to a longer wavelength. The apparent quenching of PEPC fluorescence was observed in the fullerenated polymer and it can be attributed to intramolecular excited state energy transfer.展开更多
