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. Full article:

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
The latest from @APunLab is out now in @JMaterChem C

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 https://t.co/wH4SEWkm8Q
We are excited to share our first work @UCSanDiego on a novel family of DPND annihilators for efficient triplet fusion upconversion available @angew_chem!
Here, we provide a blueprint on structure-property relations to enhance the UC performance ↗️

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

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
