Abstract
A comparative study of the photophysical properties of pristine C70 and two C70 derivatives, including their thermally activated delayed fluorescence (TADF) is reported. It is observed that the addition of a substituent group to the C70 cage-like structure changes both the radiative and the nonradiative rate constants, the change being more pronounced for the nonradiative processes (S1→S0 internal conversion and S1→T1 and T1→S0 intersystem crossings). A new method of TADF analysis (global analysis of time-resolved and steady-state data) is presented and applied. Both derivatives are found to display a less efficient TADF when compared with C70.
