摘要：
Time-resolved fluorescence studies of an electron donor-acceptor modified helical oligopeptide, in acetonitrile, show a biexponential decay with a short lifetime component attributed to rapid photoinduced electron transfer (PET), which increases from 15% of the total fluorescence at -40 degrees C to 58% on warming to 0 degrees C and then more gradually to 67% at 60 degrees C.
