A Versatile Heterometallic Microporous MOF for Photocatalytic Hydrogen Generation

open access: yesSmall, EarlyView.
This work describes a green and scalable approach to robust and flexible heterometallic MOFs, MIP‐215's, with tunable photoactivity for efficient, noble‐metal‐free solar hydrogen production. ABSTRACT Photocatalytic particulate systems offer a cost‐effective solar hydrogen production but are generally limited by narrow visiblelight absorption and poor ...

Carbon monoxide‐triggered near‐infrared photoacoustic‐fluorescent integrated visualization tool for auxiliary diagnosis of heart failure and evaluation of reversal drug efficacy

open access: yesSmart Molecules, EarlyView.
An activatable metal‐free probe CS‐CO enables the first non‐invasive photoacoustic/fluorescence visualization of carbon monoxide (CO) fluctuations during heart failure and its reversal, linking CO levels directly to disease status. Abstract Heart failure (HF), a major global health challenge with high morbidity and mortality, lacks effective biomarkers

Visible‐light‐promoted catalyst‐free benzylic C‐H oxidation using molecular oxygen as a green oxidant

open access: yesSmart Molecules, EarlyView.
A green and simple photo‐oxygenation of benzylic C‐H bond with molecular oxygen was developed for the preparation of a series of carbonyl compounds. The straightforward C‐H carbonylation strategy features catalyst‐ and additive‐free reaction conditions, only oxygen as a green oxidant, broad scope and scalable, and the simple‐operation nature.
