Efficient light emission and photon absorption in the same organic molecule to advance OLEDs, medical imaging and wearable sensors


"CzTRZCN: thermally activated delayed fluorescence by producing light from normally lost heat, leading to brighter/ more energy-efficient OLEDs... absorbs 2 lower-energy photons simultaneously from high-intensity laser, reaching excited state emitting fluorescence... lower-energy photons/ longer wavelengths ideal for biomedical imaging penetrating deeper/ only small portion of tissue at focal point excited without scattering... combines electron-rich carbazole with electron-deficient triazine core"
