Measurement of ML: Pressure was applied to the single crystalline solid sample of 1 grown from THF/Et 2 O, the resulting emitted light was guided to the spectrograph via optical fiber, and the time-integrated emitting spectrum was recorded as the ML spectrum. The schematic layout for ML detection is illustrated in Figure .
