Abstract: The dispersing states of C₆₀ molecules in mixed monolayers of TDPP/C₆₀(1:1) and TAPP/C₆₀(1:1)have been studied in this paper,Here,TDPPdenotes 5,10,15,20-tetra-4-oxy(decanoic acid)phenylporphyrin, and TAPPdenotes 5,10,15,20-tetra-4-oxy(acetic acid)phenylporphyrin,The π-A isotherms of mixed monolayers on air/Cd²⁺ aqueous solutioninterface, the low angle X-ray diffraction results of the alternate multilayers of TDPPor TDPP/C₆₀ with arachidic acid and the UV-Vis spectra of mixed LBmonolayers show that,in the mixed TDPP/C₆₀ monolayer C₆₀ aggregates or(and) single C₆₀.molecules are incorporated into the cavities of TDPPmolecules containing long alkyl chains,.but in the mixed TAPP/C₆₀ monolayer, C₆₀ aggregates distribute among the TAPPaggregates.

Key words: C₆₀, Porphyrin derivative, Monolayer film
