摘要

Thin films consisting of a fulleropyrrolidine derivative 1 and a novel water-soluble porphyrin 2 were prepared by the Langmuir-Shafer(LS,horizontal lifting)method.In particular,a solution of 1 in chloroform and dimethyl sulfoxide was spread on the water surface,while porphyrin 2(bearing peripheral anionic groups)was dissolved into the aqueous subphase.To the best of our knowledge,such a versatile method of film fabrication for fullerene/porphyrin mixed composite films has never been used before.Evi-dence of the effective interactions between the two moieties at the air-water interface was obtained from the analysis of the floating layers by means of surface pressure versus area per molecule Langmuir curves,Brewster angle microscopy and UV-visible reflection spectroscopy.The characterisation of the LS films by UV-visible spectroscopy reveals that the two constitu- ents behave as discrete and weakly interacting it systems.The use of polarised light suggests the existence of a preferential direction of the macrocy-clic rings with an edge-on arrangement with respect to the substrate surface.Finally,photoaction spectra were recorded from films deposited by only one horizontal lifting onto indium-tin-oxide(ITO)electrodes and the observed photocurrent increased notably with increasing transfer surface pressure.
