Multi‐Level Confinement Single‐Molecule Charge Transfer Activated PRET for Near‐Infrared Targeted Cell Imaging

Advanced Science, EarlyView.
The cascade supramolecular assembly of charge‐transfer arrays not only triggered a topological transformation from nanofiber to nanorod and vesicles, but also promoted single‐molecule phosphorescent resonance energy transfer, expanding phosphorescence emission at 500 nm to near‐infrared delayed fluorescence emission at 650 nm with a lifetime of 11.20 ...

Mechanism of H_2 Evolution from a Photogenerated Hydridocobaloxime [PDF]

, 2010
Proton transfer from the triplet excited state of brominated naphthol to a difluoroboryl bridged Co^I-diglyoxime complex, forming Co^(III)H, was monitored via transient absorption. The second-order rate constant for Co^(III)H formation is in the range (3.

An All‐in‐One Lignin‐Based Artificial Thylakoid Nanovesicle Via In‐Situ Confined Growth Strategy for High‐Efficient and Selectivity CO2 Photoreduction

Carbon Energy, EarlyView.
The low light/CO2 capture and slow dynamic transfer of photogenerated electrons hamper photocatalysts’ high activity and selectivity. Inspired by the chloroplast's photosynthesis mechanism, an all‐in‐one lignin‐based artificial thylakoid nanovesicle (AiO‐L‐ATN) is constructed using a confined growth strategy of lignin molecules. The performance of such

Sterol 3β-glucosyltransferase biocatalysts with a range of selectivities, including selectivity for testosterone [PDF]

, 2013
The main objectives of this work were to characterise a range of purified recombinant sterol 3β-glucosyltransferases and show that rational sampling of the diversity that exists within sterol 3β-glucosyltransferase sequence space can result in a range of

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
