Summary: A naphthalimide functionalized fluoran dye NAF has been prepared, which exhibits a red-shift in emission at 550 nm in a water-CH3CN mixture due to aggregating induced emission (AIE) effect. NAF can function as a selective and sensitive sensor for Hg2+ ions by displaying a ratiometric fluorescence signal change and visible color change. It shows fast response time, wide pH range, and low detection limit, making it suitable for ratiometric imaging of Hg2+ ions in living HeLa cells.

Summary: A highly selective ratiometric fluorescent chemodosimeter was synthesized for the detection of Hg2+, which showed remarkable detection properties including high selectivity and sensitivity, large fluorescent signal changes, and well-operation in aqueous solutions. The displacement reaction between phenylboronic acid and Hg2+ ions provided a covalent adduct of mercury ion, leading to significant fluorescent signal changes when aggregated in aqueous solution. With a low detection limit of 15.2 nM, nanomolar concentrations of Hg2+ could be successfully detected, providing a ratiometric fluorescent detection method for quantifying low levels of Hg2+ in groundwater and tap water samples.

Summary: In this study, a Dyad compound NI-SP with 1,8-naphthalimide (NI) and styrylpyridine (SP) photoactive units was evaluated as a ratiometric fluorescent chemosensor for mercury (II) ions in living cells.

Summary: Aggregation-induced emission (AIE) based fluorescent organic nanoparticles (FONPs) are superior sensors with easy fabrication, high signal-to-noise ratio, and good biocompatibility. This article focuses on the detection and analysis of the redox behavior of the protein disulfide isomerase (PDI) enzyme using novel naphthalimide (NI) derivatives with thiol and disulfide moieties. The synthesized NI-based amphiphiles (NISH, NISS, NINSS, and TNINSH) formed self-aggregated spherical-shaped organic nanoparticles, exhibiting AIE in DMSO-water. The NINSS and TNINSH FONPs were successfully utilized for sensing PDI through their thiol-disulfide exchange and showed high efficiency with limits of detection of -12.6-17.7 and -11.7-16.5 ng/mL, respectively. In vitro cell imaging with NINSS and TNINSH FONPs displayed excellent diagnosis of eukaryotic cells, particularly cancer cells, due to the overexpression of PDI.

However, highly sensitive temperature sensing with organic fluorescent nanothermometers is challenging. In this study, a ratiometric fluorescent nanogel thermometer is developed to determine bactericidal temperature. The nanogel exhibits reversible spectral changes based on its hydrophilic-to-hydrophobic transition, and its emission intensity can be correlated to external temperature. The nanogel shows promise in predicting photothermal antibacterial effects and other temperature-related biological events.

Summary: Sable organic radicals hold great promises for various applications such as information storage, molecular magnetism, electronic devices, and biological probes. However, most organic radicals synthesized so far are non- or weakly emissive and easily degrade upon photoexcitation. This study presents a photoactivation approach to produce a stable and luminescent radical from tris(4-chlorophenyl)phosphine, which emits red light in the crystal state. The mechanism study reveals that breaking of molecular symmetry in the crystal leads to changes in molecular conformation, redox properties, and molecular packing, which facilitate the generation and stabilization of the radical. This design strategy provides a straightforward method to develop stable organic luminescent radicals and paves the way for photoinduced luminescent radical materials.

Summary: Phototheranostic agents, integrating sensitive in situ fluorescence imaging and effective multi-model synergistic therapy, have emerged as promising tools for cancer theranostics. However, balancing the competitive radiative and nonradiative processes in photon energy transfer remains challenging. In this study, three simple molecules with electron donating-accepting structures were developed. The introduction of an acridinium unit as an electron acceptor led to the formation of TPEDCAc with aggregation-induced second near-infrared emission, high reactive oxygen species generation capability, and excellent photothermal conversion efficiency. The key factors for achieving NIR-II emission and balanced photodynamic/photothermal conversion were found to be large torsional angle and strong electron-withdrawing ability of the acridinium unit. Impressively, TPEDCAc exhibited mitochondria-targeting capability and high performance in in vivo multi-modal cancer theranostics under NIR laser irradiation. This work not only provides a single NIR-II AIE-based multi-modal cancer theranostic system but also inspires new insights into the development of theranostic platforms in the future.

Summary: A new near-infrared thioxanthene-hemicyanine dye (Cy-DNBS) has been developed for simultaneous fluorescence and photoacoustic imaging of biothiols. Upon treatment with biothiols, Cy-DNBS exhibits strong near-infrared absorption and a subsequent turn-on photoacoustic signal. Additionally, the fluorescence intensity of Cy-DNBS increases instantly. The dye has been successfully used for imaging endogenous and exogenous biothiols in cells and mice, as well as tracking biothiols upregulation in the liver of mice triggered by S-adenosyl methionine. Cy-DNBS shows great potential for studying biothiols-related physiological and pathological processes.

Summary: Poly(vinyl alcohol) (PVA) is used as a matrix to enhance the room-temperature phosphorescence (RTP) of chromophores by forming abundant hydrogen bonding. The role of PVA in manipulating the excited-state energy level to facilitate multiple intersystem crossing channels is investigated. The PVA matrix allows a broad distribution of charge-transfer states, providing multiple pathways for intersystem crossing via spin-vibronic orbit coupling. Consequently, heavy-atom-free phosphors with high quantum yields (7.7%) and long lifetime (2.3 s) have been developed.

Summary: Drug-induced liver injury (DILI) is a common cause of acute liver failure in the USA and Europe, but most cases can be recovered or prevented by discontinuing the offending drug. Recent research has found that peroxynitrite (ONOO-) can be used as a potential indicator for early diagnosis of DILI, and there is an urgent need to establish a method to detect and track peroxynitrite in DILI cases. In this study, a FRET-based nano fluorescent probe CD-N-I was developed, which showed high selectivity and sensitivity in detecting peroxynitrite. The probe successfully detected exogenous peroxynitrite in live cells and endogenous peroxynitrite in APAP-induced liver injury of HepG2 cells.
