Thermally Activated Delayed Fluorescence: Polarity, Rigidity, and Disorder in Condensed Phases (2022)
Journal Article
Phan Huu, D. A., Saseendran, S., Dhali, R., Gomes Franca, L., Stavrou, K., Monkman, A., & Painelli, A. (2022). Thermally Activated Delayed Fluorescence: Polarity, Rigidity, and Disorder in Condensed Phases. Journal of the American Chemical Society, 144(33), 15211 - 15222. https://doi.org/10.1021/jacs.2c05537

We present a detailed and comprehensive picture of the photophysics of thermally activated delayed fluorescence (TADF). The approach relies on a few-state model, parametrized ab initio on a prototypical TADF dye, that explicitly accounts for the nona...

Laplace Transform Fitting as a Tool To Uncover Distributions of Reverse Intersystem Crossing Rates in TADF Systems (2022)
Journal Article
Kelly, D., Gomes Franca, L., Stavrou, K., Danos, A., & Monkman, A. P. (2022). Laplace Transform Fitting as a Tool To Uncover Distributions of Reverse Intersystem Crossing Rates in TADF Systems. Journal of Physical Chemistry Letters, 13(30), 6981-6986. https://doi.org/10.1021/acs.jpclett.2c01864

Donor–acceptor (D–A) thermally activated delayed fluorescence (TADF) molecules are exquisitely sensitive to D–A dihedral angle. Although commonly simplified to an average value, these D–A angles nonetheless exist as distributions across the individua...
