Photocatalysis under UV/visible light irradiation has emerged as one of the green methodologies for solar energy utilization and organic synthesis. These photocatalytic processes are typically initiated by one-photon-absorbing metal complexes or organic dyes. Nevertheless, the intrinsic restrictions of UV/visible light irradiation, such as shallow penetration in reaction solutions, competing absorption by substrates, and limited coverage of the solar spectrum, call for the development of innovative photocatalysts functioning under longer wavelength irradiation Herein, we report a ruthenium complex containing a metal-organic framework, MOF-Ru1, which can drive diverse organic reactions under 740 nm light irradiation following the two-photon absorption (TPA) process. Various organic transformations such as energy transfer, reductive, oxidative, and redox neutral reactions were realized using this heterogeneous hybrid photocatalyst. Overall, MOF-Ru1 represents an intriguing TPA photocatalyst active under near-IR light irradiation, paving a way for the efficient utilization of low-energy light and convenient photocatalyst recycling because of phase separation

Metal decorated-mesoporous carbons (MMCs) has attractive features from both mesoporous materials (large pore size, high pore volume) and metal species (reactive surface). Cobalt@mesoporous carbon (Co@MC) catalyst was successfully manufactured by mechanochem. synthesis method for hydrogenation of phenol to prepare cyclohexanone. Unlike traditional hard-templating and soft-templating methods, the essence of this strategy lies in the combination of carbonization and ligand-protected metal reduction By using Fourier transform-IR spectroscopy, X-ray diffraction and N₂ adsorption-desorption, Co@MC catalyst was well studied. In particular, the effect of calcination temperature in terms of growth and aggregation of cobalt species was detailly explored by in-situ scanning transmission electron microscopy-high angle angular dark field. A series of mesoporous carbons with cobalt species readily tuned from clusters to nanoparticles were measured in phenol hydrogenation (Conv. Phenol: >99 %, Sel. Cyclohexanone: >99 %).

Sun, Yaru;Tang, Xiaochan;Li, Xiaobing;Kong, Xiuqi;Tian, Minggang;Wang, Yue;Dong, Baoli research published 《 PET-ESIPT-based fluorescent probes for revealing the fluctuation of peroxynitrite (ONOO^–) in living cells, zebrafishes and brain tissues》, the research content is summarized as follows. Peroxynitrite (ONOO^–) plays crucial roles in a variety of physiol. and pathol. processes in living systems, and therefore, real-time and in situ imaging of ONOO^– is of great significance to in-depth study its biol. roles. Herein, we have developed PET-ESIPT-based fluorescent probes (BCN and BCN-A) for the detection of ONOO^– in living cells, zebrafishes and brain tissues. BCN was a highly sensitive ONOO^– probe in which the fluorescence property of the fluorophore was simultaneously controlled by PET and ESIPT mechanisms, and transformed to BCN-A via acetylation. Especially, BCN showed large Stokes shift in response to ONOO^–, and displayed high selectivity to ONOO^–. BCN-A employed the acetate group to switch off ESIPT process of the fluorophore and improve the membrane permeability. In living cells, BCN-A released an ONOO^–-responsive probe (BCN) by the hydrolysis of esterase, and then detected ONOO^–. Biol. imaging demonstrated that although both metformin and rotenone are mitochondrial complex I inhibitors, metformin can increase the generation of ONOO^– while rotenone had no significant influence on the generation of ONOO^– in living cells and zebrafishes. Moreover, the amygdala and perirhinal/entorhinal cortex in the brain of depressive mouse both showed increasing fluorescence intensity relative to those of normal mouse, which suggested that the LPS-induced depressive disorder could result in the generation of ONOO^– in the two brain areas of mouse. We expect that the probes (BCN and BCN-A) could extensively serve as the powerful mol. tools to investigate the biol. roles of ONOO^– for the in-depth study of drug mechanism and depressive disorder.

The cyclization-coupling reaction of 2-bromoaryl ketones 2-Br-4-R-5-R¹C₆H₂C(O)Me (R = H, Cl, F, MeO; R¹ = H, Cl, Me), 1-(pyridin-3-yl)ethan-1-one and terminal alkynes R²CCH (R² = Ph, 4-bromophenyl, pyridin-3-yl, etc.) is first realized by copper catalysis, which produces polyfunctional naphthyl aryl ethers I (X = CH, N) in moderate to excellent yields with broad substrate scope and good functional group tolerance. This reaction proceeds via 6-endo-dig cyclization and C(sp²)-O coupling using green H₂O as the unique solvent and 5-bromopyrimidin-2-amine as the critical additive.

Strauss, Marie E.;Santaloci, Taylor J.;Fortenberry, Ryan C. research published 《 Valence-, Dipole- and Quadropole-Bound Electronically Excited States of Closed-Shell Anions Formed by Deprotonation of Cyano- and Ethynyl-Disubstituted Polycyclic Aromatic Hydrocarbons》, the research content is summarized as follows. Dicyano-functionalized benzene and naphthalene anion derivatives exhibit a relatively rich population of electronically excited states in stark contrast to many assumptions regarding the photophysics of anions in general. The present work has quantum chem. analyzed the potential electronically excited states of closed-shell anions created by replacing hydrogen atoms with valence-bound lone pairs in benzene and naphthalene difunctionalized with combinations of -CN and -C₂H. Dicyanobenzene anion derivatives can exhibit dipole-bound excited states as long as the cyano groups are not in para position to one another. This also extends to cyanoethynylbenzene anions as well as deprotonated dicyano- and cyanoethynylnaphthalene anion derivatives Diethynyl functionalization is less consistent. While large dipole moments are created in some cases for deprotonation on the -C₂H group itself, the presence of electronically excited states beyond those that are dipole-bound is less consistent. Beyond these general trends, 2-dicyanonaphthalene-34 gives strong indication for exhibiting a quadrupole-bound excited state, and the 1-cyanoethynylnaphthalene-29 and -36 anion derivatives are shown to possess as many as two valence-bound excited states and one dipole-bound excited state. These photophys. properties may have an influence on regions where polycyclic aromatic hydrocarbons are known to exist such as in various astrochem. environments or even in combustion flames.
