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 ...

Double-bond delocalization in non-alternant hydrocarbons induces inverted singlet-triplet gaps

Marc Hamilton Folkmann Garner, Jacob Terence Blaskovits

Molecules where the first excited singlet state is lower in energy than the first excited triplet state have the potential to revolutionize OLEDs. This inverted singlet-triplet gap violates Hund's rule and currently there are only a few molecules which are ...

Impact 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 ...

Single molecule fluorescence and phosphorescence studies using a scanning tunneling microscope

Abhishek Grewal

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 ...

A general framework for non-exponential delayed fluorescence and phosphorescence decay analysis, illustrated on Protoporphyrin IX

Georges Wagnières, Jaroslava Joniová, Emmanuel Louis Arthur Gerelli, Aurelien Stephen Arnaud Gregor

Delayed fluorescence (DF) is a long-lived luminescence process used in a variety of applications ranging from oxygen sensing in biological tissues to organic Light Emitting Diodes. In common cases, DF results from the deexcitation of the first excited trip ...

Superexchange mechanism and quantum many body excitations in the archetypal di-Cu oxo-bridge

Edward Baxter Linscott, Cédric Weber

The hemocyanin protein binds and transports molecular oxygen via two copper atoms at its core. The singlet state of the Cu2O2 core is thought to be stabilised by a superexchange pathway, but detailed in situ computational analysis is complicated by the mul ...

Microwave-Cavity-Detected Spin Blockade in a Few-Electron Double Quantum Dot

Pasquale Scarlino

We investigate spin states of few electrons in a double quantum dot by coupling them to a magnetic field resilient NbTiN microwave resonator. The electric field of the resonator couples to the electric dipole moment of the charge states in the double dot. ...

Revising the common understanding of metamagnetism in the molecule-based bisdithiazolyl BDTMe compound

Sergio Vela Llausi

The BDTMe molecule-based material is the first example of a thiazyl radical to exhibit metamagnetic behavior. Contrary to the common idea that metamagnetism occurs in low-dimensional systems, it is found that BDTMe magnetic topology consists of a complex 3 ...
