Abstract Photoredox catalysis relies on light-induced electron transfer leading to a radical pair comprising an oxidized donor and reduced acceptor in solvent cage. For productive onward reaction occur, the must escape from that cage before they undergo spontaneous reverse transfer. Here we show decisive role plays three benchmark photocatalytic reactions, namely, aerobic hydroxylation, reductive debromination aza-Henry reaction. Using ruthenium(II)- chromium(III)-based photocatalysts, which...
Abstract The recently reported luminescent chromium(III) complex 1 3+ ([Cr(ddpd) 2 ] ; ddpd= N , ′‐dimethyl‐ ′‐dipyridine‐2‐yl‐pyridine‐2,6‐diamine) shows exceptionally strong near‐IR emission at 775 nm in water under ambient conditions ( Φ =11 %) with a microsecond lifetime as the ligand design effectively eliminates non‐radiative decay pathways, such photosubstitution, back‐intersystem crossing, and trigonal twists. In absence of energy acceptors, dioxygen, remaining pathways are transfer...
Abstract Inorganic nanomaterials endowed with hierarchical chirality could open new horizons in physical theory and applications because of their fascinating properties. Here, we report chiral ZnO films coated on quartz substrates a nanostructure ranging from atomic to micrometer scale. Three levels exist the films: helical crystalline structures that form primary helically coiled nanoplates, secondary stacking these tertiary nanoscale circinate aggregates formed by several stacked...
Gaining chemical control over the thermodynamics and kinetics of photoexcited states is paramount to an efficient sustainable utilization photoactive transition metal complexes in a plethora technologies. In contrast energies charge transfer described by spatially separated orbitals, spin-flip cannot straightforwardly be predicted as Pauli repulsion nephelauxetic effect play key roles. Guided multireference quantum calculations, we report novel highly luminescent emitter with chemically...
Sensitized triplet-triplet annihilation upconversion (sTTA-UC) mainly relies on precious metal complexes thanks to their high intersystem crossing (ISC) efficiencies, excited state energies, and lifetimes, while of abundant first-row transition metals are only rarely utilized with often moderate UC quantum yields.

The Warburg effect or aerobic glycolysis is a hallmark of cancer. Lactate dehydrogenase (LDH), which catalyzes conversion pyruvate into lactate, serves critical role during effect. LDH A chain (LDHA), member the family, upregulated in multiple types cancer and vital tumor growth progression. However, its expression function cervical has not been characterized. present study evaluated LDHA Cancer Genome Atlas database found that was compared with normal tissue. To clarify HeLa SiHa cells,...
The environmental impacts of genetically modified (GM) plants remain a controversial global issue. To address these issues, comprehensive risk assessments GM is critical for the sustainable development and application transgenic technology. In this paper, significant differences were not observed between microbial metagenomic metabolomic profiles in surface waters Bt rice (T1C-1, line) non-Bt cultivars (Minghui 63 (the isogenic Zhonghua 11 conventional japonica cultivar)). contrast, apparent...
Microencapsulated phase change materials (MicroPCM) were successfully fabricated by encapsulation of sodium thiosulfate pentahydrate (SoTP) as core with silica shell using sol–gel method.
Upconversion photoluminescence in hetero-oligonuclear metal complex architectures featuring organic ligands is an interesting but still rarely observed phenomenon, despite its great potential from a basic research and application perspective. In this context, new photonic material consisting of molecular chromium(III) ytterbium(III) ions was developed that exhibits excitation-power density-dependent cooperative sensitization the chromium-centered 2 E/2 T1 phosphorescence at approximately 775...
Two nanosensors for simultaneous optical measurements of the bioanalytically and biologically relevant analytes temperature ("T"), oxygen ("O"), pH ("P") have been designed. These "TOP" are based on 100 nm-sized silica-coated polystyrene nanoparticles (PS-NPs) doped with a near-infrared emissive oxygen- temperature-sensitive chromium(III) complex ([Cr(ddpd)2][BPh4]3, CrBPh4) an inert reference dye (Nile Red, NR or 5,10,15,20-tetrakis(pentafluorophenyl) porphyrin, TFPP) covalently labeled...
In this work, we describe the synthesis, structural and photophysical characterization of four novel Pd(ii) Pt(ii) complexes bearing tetradentate luminophoric ligands with high photoluminescence quantum yields (Φ L) long excited state lifetimes (τ) at room temperature, where results were interpreted by means DFT calculations. Incorporation fluorine atoms into ligand favors aggregation thereby, a shortened average distance between metal centers, which provides accessibility to...
Sensitized triplet–triplet annihilation upconversion is a promising strategy to use visible light for chemical reactions requiring the energy input of UV photons. This avoids unsafe ultraviolet sources and can mitigate photo-damage provide access reactions, which filter effects hamper direct excitation. Here, we report new approach make blue-to-UV more amenable photochemical applications. The tethering naphthalene unit cyclometalated iridium(III) complex yields bichromophore with high...
Photosensitizers for sensitized triplet-triplet annihilation upconversion (sTTA-UC) often rely on precious heavy metals, whereas coordination complexes based abundant first-row transition metals are less common. This is mainly because long-lived triplet excited states more difficult to obtain 3d particularly when the d-subshell only partially filled. Here, we report first example of sTTA-UC a 3d6 metal photosensitizer yielding an performance competitive with metal-based analogues. Using...
