| Abstract |
Although the highly unusual case of excited state intramolecular proton transfer (ESIPT) of quinophthalone (QPH) has recently been reported in some detail, the relaxation pathway to the ground state after the ESIPT remains elusive to date. Moreover, the fact that the excited-state lifetimes and spectral bands are not fully explained indicates that additional states and/or processes may be involved in its excited state dynamics. In order to map out the complete picture for the complex photophysics of QPH, we conducted various spectroscopic experiments including ultrafast time-resolved transient absorption spectroscopy in different reaction environments. |
