| Abstract: | A novel amphiphilic triad compound was synthesized by linking viologen with zinc phthalocyanine and ferrocene by flexible chains.Absorption and fluorescence spectra as well as fluorescence lifetime have been determined.Time resolved transient absorption spectrum and time profile measurements show that photoinduced intramolecular electron transfer in the triad is more efficient than that in dyad, giving a final long-living charge-separated state with longer lifetime beyond 100 μs.A mechanism of two-step charge separation process was suggested.The thin films of the triad compound molecules in monolayer and multilayers were successfully deposited on SnO2 substrate and photoelectric effect of the LB films were observed. |
