Extended Data Fig. 2: HOMO and LUMO of organic scintillators.

Highest occupied molecular orbitals (HOMO) and lowest unoccupied molecular orbitals (LUMO) according to the results of time-dependent DFT for the S1 states of Anthracene, DMAc-TRZ, 4CzIPN and 4CzTPN-Bu using the optimized structure of the S0 states. Colors indicate the different phases of the natural transition orbitals.
