The photophysical properties of PyTS have been studied by steady-state absorption
fluorescence emission and time-resolved transient absorption spectroscopies. PyTS has a high fluorescence quantum yield in water
Φ-=0.54. The PyTS triplet state lifetime we obtained is 3.5 ms from nanosecond transient absorption spectra
its long lifetime is much favourable for excited energy transfer to other molecules as a sensited molecule. It maybe occurs a two photon absorption process which leads to PyTS cation transient absorption at 460 nm and 505 nm when PyTS-was excited. Here we also proposed the dynamic scheme of PyTS from the experimental results.
