Hi everyone, I am studying the photoluminescence (PL) quenching of a complex A1-D-A2. After using electron-hole analysis, for the 1st state, the electron transfers to A1, and for the 2nd state, the electron transfers to A2; both are dark states. Can I ask which one will cause PL quenching? In the experiment, the A2 had better electron withdrawing ability. Thank you
anything and everything can cause photoluminescence quenching. A huge problem in PL is stable room temperature and not equilibrating the detector long enough. if you are using any kind of flow, gradient profile, you cannot do that in PL, only isocratic systems with overnight equilibration will give stable and Reproducible results. you have to run at elevated controlled temperature. PL is a pain in the ass.
