Dispersion of C-60 in mixed Langmuir monolayers of porphyrin/C-60

The dispersing states of C-60 molecules in mixed monolayers of TDPP/C-60 (1:1) and TAPP/C-60 (1:1) have been studied in this paper. Here, TDPP denotes 5,10,15,20-tetra-4-oxy(decanoic acid)phenylporphyrin, and TAPP denotes 5,10,15,20-tetra-4-oxy (acetic acid)phenylporphyrin. The pi-A isotherms of mixed monolayers on air/Cd2+ aqueous solution interface, the low angle X-ray diffraction results of the alternate multilayers of TDPP or TDPP/C-60 with arachidic acid and the UV-Vis spectra of mixed LB monolayers show that, in the mixed TDPT/C-60 monolayer C-60 aggregates or (and) single C-60 molecules are incorporated into theaggregates or(and) single C-60 molecules are incorporated into the cavities of TDPP molecules containing long alkyl chains, but in thr mixed TAPP/C-60, monolayer, C-60 aggregates distribute among the TAPP aggregates.
