Till defended his PhD thesis today.🍾 Extremely convincing discussion and great performance resulted in degree with highest distinction💪. All the best for your postdoc in Bologna, where Giacomo Ciamician did pioneering work in #photochemistry. Curious to see what Till will do 🤔

Julian's manuscript dealing with a novel biphenyl annihilator and unusual effects of different substituents. Is it a new benchmark system for blue-to-UV upconversion? You can read about it here: https://t.co/25B0SoXORv

Unbelievable milestone for our group with a new publication in the prestigious @ACSCentSci ! Electron transfer, not energy transfer is controlling population of the final triplet state in a Fe(III)-PhAn dyad! @CadraLab @Gio_Ben_ @frsFNRS @WELRI_asbl

An iron-anthracene dyad was recently used to populate a microsecond-lived nonluminescent (dark) triplet state, but with a surprisingly low triplet population yield. In-depth spectroscopic experiments...

Organic molecules can have multiple photo-accessible spin manifolds? In our paper in @NatureChemistry we show how you can read and write spin-dependent information in a unique organic molecule using photons! https://t.co/U0zdNJDGHe Next up: Room Temperature control!😉

Check out our new paper on TTA photon upconversion toward UVC energy generation using TIPS‐benzene as an emitter and heptazine as a sensitizer in Adv Opt Mater @AdvPortfolio. Nice collaboration with @Naoya_Aizawa. Congrats Masanori! https://t.co/c1G1g1FANz

We show how photoredox catalysis can bypass Kasha’s rule, enabling reactions from higher excited states. This work, led by the exceptional @BjornPfund, offers new insights into photochemical reactivity. Published in @J_A_C_S: https://t.co/4waiPatQKZ

Just out in @angew_chem: a thorough look at an isolated acridinyl radical and its conPET-type photochem., with an emphasis on understanding how SET takes place. (Dynamic quenching? Preassembly? Solvated electrons?) Thanks to collaborators @RCNSTheoChem! https://t.co/kJ5j7gdDOb

In this paper, we isolate the reduced form of a commonly used acridinium photocatalyst (acridinyl, Acr•) and investigate its photochemistry using transient absorption, analysed alongside TD-DFT...

The next masterpiece from Matthias focusing on Coulombic dyads as new #photocatalyst class has been accepted in @angew_chem. Higher quantum yields in red-light catalysis by adding an inexpensive salt to use #Os as efficiently as possible. https://t.co/4sSaMfUzht

Triplet–triplet annihilation photon upconversion (TTA-UC) provides a milder alternative to traditional UVB/UVC photochemistry. However, suitable sensitizer-annihilator pairs are scarce, in particular...

One photon or two photons, that is the question. We discuss mechanistic challenges, pitfalls, and opportunities for future research in two-photon photocatalysis @angew_chem. Many thanks to first-authors Julian and Sophie. https://t.co/0zAw99S63r
