Spontaneous exciton dissociation enables spin state interconversion in delayed fluorescence organic semiconductors

Autor: Gillett, Alexander J., Tonnelé, Claire, Londi, Giacomo, Ricci, Gaetano, Catherin, Manon, Unson, Darcy M. L., Casanova, David, Castet, Frédéric, Olivier, Yoann, Chen, Weimin M., Zaborova, Elena, Evans, Emrys W., Drummond, Bluebell H., Conaghan, Patrick J., Cui, Lin-Song, Greenham, Neil C., Puttisong, Yuttapoom, Fages, Frédéric, Beljonne, David, Friend, Richard H.

Engineering a low singlet-triplet energy gap ({\Delta}EST) is necessary for efficient reverse intersystem crossing (rISC) in delayed fluorescence (DF) organic semiconductors, but results in a small radiative rate that limits performance in LEDs. Here

Electron spin resonance resolves intermediate triplet states in delayed fluorescence

Autor: Drummond, Bluebell H., Aizawa, Naoya, Zhang, Yadong, Myers, William K., Xiong, Yao, Cooper, Matthew W., Barlow, Stephen, Gu, Qinying, Weiss, Leah R., Gillett, Alexander J., Credgington, Dan, Pu, Yong-Jin, Marder, Seth R., Evans, Emrys W.

Molecular organic fluorophores are currently used in organic light-emitting diodes, though non-emissive triplet excitons generated in devices incorporating conventional fluorophores limit the efficiency. This limit can be overcome in materials that h

Chemical Science

Conformationally flexible “Carbene–Metal–Amide” (CMA) complexes of copper and gold show photoemissions across the visible spectrum, including mechanochromic behavior which led to the first CMA-based white light-emitting OLED.
