Symmetry-Induced Singlet-Triplet Inversions in Non-Alternant Hydrocarbons
Marc Hamilton Folkmann Garner, Anne-Clémence Corminboeuf, Jacob Terence Blaskovits
Molecules with inversion of the singlet and triplet excited-state energies are highly promising for the development of organic light-emitting diodes (OLEDs). To date, azaphenalenes are the only class of molecules where these inversions have been identified ...
2023Impact of chlorination and ozonation of dissolved organic matter on its photo-induced production of long-lived photooxidants and excited triplet states
Urs von Gunten, Joanna Maria Houska, Silvio Canonica, Stephanie Christa Remke
Recent studies suggested that long-lived photooxidants (LLPO), which are reactive intermediates formed during irradiation of dissolved organic matter (DOM), may consist of phenoxyl radicals derived from phenolic moieties of the DOM. Besides the well-studie ...
PERGAMON-ELSEVIER SCIENCE LTD2023Single molecule fluorescence and phosphorescence studies using a scanning tunneling microscope
This thesis investigates novel single-molecule luminescence phenomena at their inherent, sub-molecular length scale. The microscopic understanding of luminescence processes will be crucial for the continued improvement of organic optoelectronic and semicon ...
EPFL2022Donor-Acceptor-Donor "Hot Exciton" Triads for High Reverse Intersystem Crossing in OLEDs
Sergio Vela Llausi, Maria Fumanal Quintana, Yanan Zhu
Hot exciton materials have the potential to improve the quantum efficiency of organic light-emitting diodes (OLEDs) by promoting high reversed intersystem crossing (hRISC) between a high-lying triplet (T-n, n >= 2) and a radiative singlet (S-m). In recent ...
WILEY-V C H VERLAG GMBH2022Understanding delayed fluorescence and triplet decays of Protoporphyrin IX under hypoxic conditions
Photosensitizers of singlet oxygen exhibit three main types of reverse intersystem-crossing (RISC): thermally activated, triplet-triplet annihilation, and singlet oxygen feedback. RISC can be followed by delayed fluorescence (DF) emission, which can provid ...
