Dual fluorescence behavior of zinc 5,10,15,20-tetra(p-bromophenyl)porphine (ZnTPPBr) has been studied using absorption and fluorescence spectroscopy. Bimolecular fluorescence quenching reactions between ZnTPPBr and fullerene/ferrocene indicate that quenching behavior of S2 state may be partially transferred and preserved in S1 state so as to finally influence S1 state. The result is similar to the phenomenon that electron spin polarization of radical or triplet species produced in the precursor can be transferred and preserved in the products in CIDEP. Our work provides a novel method for investigating upper excited state with a short lifetime and low fluores-cence quantum yields.
