The @Yanai_Lab new website is now live! This site embodies our desire to pursue new interdisciplinary research in Tokyo alongside members from diverse backgrounds. Special thanks to @yap0512 for bringing this vision to life through their design! yanailab.chem.s.u-tokyo.ac.jp/en/

The 30th @GDCh_aktuell Photochemistry conference (LCP) is approaching and will take place in beautiful Braunschweig in September. It includes five plenary lectures by well-respected speakers, as well as two prestigious award lectures. Visit gdch.de/photo2026 for details.

@WerzLab @iiserkol @UniFreiburg @FreiburgChem Impressive results, Daniel and co-authors. I should perhaps rethink about N20 activation, which I used to trap hydrated electrons during my PhD studies a couple of years ago 😅

We have never thought that our BOIMPYs would get so prominent in photocatalysis: carboxylative Birch and activation of N2O. Great collaboration of the Mandal group ⁦@iiserkol⁩ with ⁦@WerzLab⁩ ⁦@UniFreiburg⁩ ⁦@FreiburgChem⁩ pubs.acs.org/doi/10.1021/ja…

A molecular dyad of an iron complex covalently bound to an annihilator exhibits three photoactive excited states — singlet, doublet, and triplet — enabling homomolecular upconversion @fDoettinger, Jonathan Sagaya, @GiacomoMorsell2 in @J_A_C_S pubs.acs.org/doi/10.1021/ja…

On my way to Basel to attend the Dreyfus Lectureship, which will be given by Jim McCusker. Sun is shining and the train is almost on time.

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 🤔

Many thanks to our collaboration partner, in particular @NobuhiroYanai and his amazing former PhD student Masanori.

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: chemrxiv.org/engage/chemrxi…

We @Yanai_Lab are pleased to announce that the 5th International Symposium on Singlet Fission and Photon Fusion (ISPF2) will be held for the first time in Asia on Sep 8–10, 2026, at the University of Tokyo, Japan. smartconf.jp/content/ispf2_… We look forward to welcoming you to Tokyo!

Amaizing lineup of invited speakers: @FNCastellano @BorjessonGroup @SoyLuisCampos @DrVic2r @GroupGuldi @GangHan_UMMS @ckerzig @schmidtim @MingLeeTang1 @WengerOliver and many others

New molecular design absorbs 2 photons to store 2 positive and 2 negative charges 100 ns lifetime, 3 eV energy storage, and 37% quantum yield A step toward multi-electron photochemistry Mathis Brändlin and @BjornPfund in @NatureChemistry nature.com/articles/s4155…

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 pubs.acs.org/doi/10.1021/ac…

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! nature.com/articles/s4155… Next up: Room Temperature control!😉

That’s a wrap for #ICP2025 in Aachen! Huge thanks to all speakers and poster presenters for the outstanding talks and engaging discussions. It was an inspiring and successful week!

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! advanced.onlinelibrary.wiley.com/doi/10.1002/ad…

@NobuhiroYanai Thank you Nobu - a nice coincidence that we submitted results with a similar system almost at the same time. Seemingly, you selected the better sensitizer ;-)

Note that @ckerzig group also independently reports the same emitter, very nice work! Let's push the limit of TTA-UC to even higher energy! pubs.rsc.org/en/content/art…

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: bit.ly/3IysmjX

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! onlinelibrary.wiley.com/doi/10.1002/an…

We are honored to welcome Prof. Dr. Dirk M. Guldi @GroupGuldi as the Event Chair of the 1st International Online Conference on Photochemistry #IOCP2026 , organized by @MDPI 📅Stay tuned for more updates! 🔗brnw.ch/21wT0xU #Photochemistry #OnlineConference #ScienceEvents
