A rod-like YbZn nanocluster was constructed, which could be an activatable NIR probe for quercetin, with a short response time (5 s) and a low detection limit (0.75 μM). Theoretical simulations reveal that strong π···π interactions and hydrogen bonding result in good orbital overlap for charge transfer from quercetin to the cluster.

Semiconducting open-shell radicals (SORs) have promising potential for the development of phototheranostic agents, enabling tumor bioimaging and boosting tumorous reactive oxygen species (ROS). Herein, a new class of semiconducting perylene diimide (PDI), designated as PDI(Br) with various numbers of bromine (Br) atoms modified on PDI's bay/ortho positions is reported. PDI(Br) is demonstrated to transform into a radical anion, [PDI(Br)], in a reducing solution, with a typical g-value of 2.

Molecular chemiluminescence probes with near-infrared (NIR) emission offer promising benefits in deciphering complex pathological processes in a living system, as NIR chemiluminescence minimizes autofluorescence, enhances deep-tissue penetration, and improves signal-to-noise ratio. Molecular engineering with single luminophore design and dual-luminophore design with intramolecular energy transfer provides way to develop conventional chemiluminophore scaffolds into NIR chemiluminescence probes with ideal chemiluminescence quantum yield and half-life. By virtue of the structural diversity, 1,2-dioxetane-based NIR chemiluminophores with biomarker activity have been developed.

Alzheimer's disease (AD), a progressive neurodegenerative disorder, is associated with the complete loss of cognition, and its pathogenesis has been suggested to be closely linked to oxidative stress in the early stage. However, there is currently a lack of effective methods to provide direct evidence for dynamic development of the oxidative stress status during AD progression. Herein, through manipulating the multiple energy transfer between 4f electronic levels of lanthanide ions (Ln), we proposed an energy interception strategy to construct activatable NIR-IIb nanoprobe for visualizing oxidative stress level.

Photocages are powerful tools for spatiotemporal control of molecule release or biological activity. However, many photocages are unsuitable for biological experiments since they are mostly activated by harmful ultraviolet (UV) light and often lack a sufficient optical readout. Thus, there is a high demand for near infrared (NIR) and/or two-photon activatable photocages with a characteristic readout.
