Flexible white thermally activated delayed fluorescence polymer with alkyl spacer and side‐chain encapsulation for efficient solution‐processed white organic light‐emitting diodes

FlexMat, EarlyView.
A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).

Quenching of alkaline phosphatase phosphorescence by O2 and NO. Evidence for inflexible regions of protein structure [PDF]

, 1987
The rate constant for quenching the phosphorescence of alkaline phosphatase by molecular oxygen was measured as a function of temperature. The results disagree with previous determinations and, contrary to fluorescence quenching, show that diffusion of ...

Triplet exciton diffusion and phosphorescence quenching in Iridium(III)-Centered dendrimers [PDF]

, 2008
A study of triplet-triplet exciton annihilation and nonradiative decay in films of iridium(III)-centered phosphorescent dendrimers is reported. The average separation of the chromophore was tuned by the molecular structure and also by blending with a ...

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

FEBS Open Bio, Volume 16, Issue 10, Page 1857-1869, October 2026.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...
