Bulky akyl substituents enhance solid-state triplet–triplet annihilation upconversion―Triplet–triplet annihilation upconversion is a process in which two low-energy photons are combined to generate a single higher-energy photon. Although this phenomenon is highly attractive for solid-state applications, most candidate systems have so far been studied primarily in solution. Now, Naimovicius, Pun @AndrewBPun et al. report in @J_A_C_S a rational molecular design strategy that progressively enhances solid-state upconversion efficiency through the incorporation of bulky alkyl substituents. By optimizing thin-film morphology, they achieve upconversion quantum yields of up to 1.5%, representing a significant step toward practical solid-state upconversion devices.

Nice back cover of the work by @KMothPoulsen, @NaimoviciusL, @twikpank et al. on “Enhancing the Statistical Probability Factor in TTA Photon Upconversion via TIPS Functionalization” in @ChemicalScience in which @calcaide_26 & @miquelsola contributed. DOI: 10.1039/d5sc05248c

Excited to share the publication of “Enhancing the Statistical Probability Factor in Triplet-Triplet Annihilation Photon Upconversion via TIPS Functionalization” in @ChemicalScience pubs.rsc.org/en/content/art…

Photoswitchable drugs offer immense #photopharmacological oportunities since the two isomers can have different pharmacological profiles. One challenge is that the #photoswitches need UV or blue light to be modulated. UV and blue light has very low penetration depth in the body

Happy Halloween from AP Lab! 🎃

@GretaBucyte We are! 😊

Hi Guys, who is coming to ACS Spring meeting?! San Diego looks really promising 😊 #ACSSpring2025

The latest from @APunLab is out now in @JMaterChem C pubs.rsc.org/en/content/art… We show electronically inactive side chains on annihilators have a major effect on the efficiency of upconversion due to steric effects Congrats to first author @NaimoviciusL and the whole team!

We demonstrate that bacterial cellulose fibers facilitate growth of functional TTA-UC crystals, which can be physically separated at the end of life, representing a crucial advancement in sustainable photonics materials @KMothPoulsen @icmabCSIC @BecarisFLC nature.com/articles/s4324…

@BaronasPaul Thank you!

@NaimoviciusL Congratulations, nice work!

Happy to be part of the team! 🎉

Today we publish: "Hybrid solar energy device for simultaneous electric power generation and molecular solar thermal energy storage" @Joule_CP cell.com/joule/fulltext… @Zhihang_Wang @HelenHoelzel @LoretteFernandz @BaronasPaul @MuhammadAdilSA @Shima__Ghasemi @JessicaOrregoH1

@twikpank @KMothPoulsen @icmabCSIC Congratulations Pankaj! 🥳

I am happy to announce that I have been awarded the Ramón y Cajal incorporation grant for a stable Researcher/Assistant Professor position in Spain aei.gob.es/sites/default/… I want to thank my Supervisors who mentored me through this competitive journey @KMothPoulsen @icmabCSIC

Kudos to @Open_Readings for giving young researchers in Lithuania(and beyond) a chance to dive into the scientific community. Happy that @light_con contributes to this conference. Personally, enjoying every second! And a shoutout to @Lukas and the OR team! #femtoinfluencer

In this work, we show how the Spin Statistical Factor of acene-based annihilators is related to the energy gap law between their 2T1 and T2 states which eventually dictates their TTA-UC quantum yields pubs.rsc.org/en/content/art… #TTA_UC @NaimoviciusL @KMothPoulsen @NobuhiroYanai

Our Review articles on "Triplet–triplet annihilation mediated photon up conversion solar energy systems" is now highlighted at the INSIDE COVER of the Journal. pubs.rsc.org/en/content/art… #PhotonUpconversion @icmabCSIC @KMothPoulsen @NaimoviciusL @DAmabilino @BecariosFLC

Effective team Enjoyyyy together #EffectiveTeam @KMothPoulsen @BaronasPaul @pedrof94 @nibaggi @LoretteFernandz @Rebecca_Salty @MorenoKevin20 @NaimoviciusL @miromila1993

In this perspective in @MaterChemFront, we review the field of #TTA-UC in context of solar energy applications. One thing that we discuss is the statistical propability factor, and how it relates to wavelength. @twikpank and @NaimoviciusL pubs.rsc.org/en/content/art…

Great pitch on ultrafast spectroscopy systems by #femtoinfluencer @GretaBucyte. Thanks for visiting us at @icmabCSIC!
