Summary: The time-resolved photocurrent response of CdSe quantum dot thin films sensitized with zinc beta-tetraaminophthalocyanine on different substrates was investigated. It was found that polyimide substrates provide larger optical bandwidth compared to glass. Evaluation of the transient photocurrent showed a combination of carrier recombination and trapping events within 2.7 ns, with less pronounced trapping events on polyimide leading to higher bandwidth.

Summary: This paper describes reversible on-off switching of the photoluminescence intensity of CdSe quantum dots mediated by photochromic furylfulgide carboxylate molecules chemisorbed to the QDs' surfaces. The switching is enabled by different rates and yields of PL-quenching photoinduced electron transfer from the QDs to the isomers, consistent with cyclic voltammetry measurements and density functional calculations. This work demonstrates fatigue-resistant modulation of the PL of a QD-molecule complex through remote control of PET, enabling potential applications like all-optical memory, sensing, and imaging with a fast, tunable, and reversible response to light stimuli.

Summary: This study demonstrates the detection of colloidal quantum dots of CdSe and CdSe/ZnS during the photooxidation of MeOH under broad spectrum illumination. The photocurrent response corresponds to single entities irreversibly adsorbing to the Pt electrode surface. The stability of nanomaterials is increased by the ZnS layer on the CdSe/ZnS material, facilitating the detection of single entities. The rate of hole transfer from QD aggregates to MeOH outcompetes the dissolution of the CdSe core under certain conditions.

Summary: The study examines ultrafast transmission changes around the fundamental trion resonance in a negatively charged II-VI quantum dot after exciting a p-shell exciton. The biexcitonic induced absorption reveals quantum beats between hot-trion states at 133 GHz. The relaxation of the P-shell hole within 390 fs dominates interband dephasing, while trionic coherence remains stored in the spin system for 85 ps due to Pauli blocking of the triplet electron.

Summary: Adding Cs to mixed-cation perovskites improves material quality and stability. Using femtosecond transient absorption spectroscopy, it is found that Cs reduces non-radiative recombination sites, increases the lifetime of photogenerated charge carriers, and slows down the cooling of hot carriers through an efficient hot-phonon bottleneck.

Summary: Protein synthesis through ribosomes is a vital process in all living organisms. However, this process can be disrupted by the removal of a single nucleobase (depurination) at the sarcin/ricin loop of the ribosomal RNA. In this study, a fluorescent probe was developed to visualize depurination. Various RNA probes were designed and characterized, which fluoresce specifically in the presence of a depurinated sarcin/ricin-loop RNA. The main challenge was to achieve a high fluorescence signal when hybridized with an abasic RNA strand, while keeping the background fluorescence low. The new RNA probes enable efficient monitoring of depurinated RNA through fluorescence intensity and lifetime measurements.

Summary: The discovery of the light-driven sodium pump Krokinobacter eikastus rhodopsin 2 (KR2) in 2013 challenged the belief that ion transport in microbial rhodopsins is limited to proton translocation. The unique retinal binding pocket in KR2, with its tight interaction between the retinal Schiff base and counterion D116, also has interesting implications for the photochemical pathway of the chromophore.

Summary: The Hula-Twist (HT) photoreaction, which involves the motion of a double bond and an adjacent single bond, is a fundamental pathway for bond isomerizations. However, the fleeting nature of HT photoproducts has hindered direct experimental observation of this coupled motion. In this study, the Dube group designed a molecular framework using sterically crowded atropisomeric hemithioindigo (HTI) to stabilize the HT photoproducts and enable their direct observation. Furthermore, the researchers investigated the ultrafast excited state processes of the HT photoreaction, providing important insights into the mechanism of complex multibond rotations in the excited state.
