Developing hydrogen-bonded organic frameworks (HOFs) that combine functional sites, size control, and storage capability for targeting gas molecule capture is a novel challenging venture. However, there lack of effective strategies to tune the network achieve high-performance HOFs. Here, series HOFs termed as HOF-ZSTU-M (M=1, 2, 3) with different pore structures are obtained by introducing structure-directing agents (SDAs) into hydrogen-bonding tetrakis (4-carboxyphenyl) porphyrin (TCPP)....
Rational control and understanding of isomerism are significance but still remain a great challenge in reticular frameworks, particular, for covalent organic frameworks (COFs) due to the complicated synthesis energy factors.

A simple, mild and efficient approach to access fluorinated dibenz[b,e]azepines via visible-light photoredox catalysis is presented. Inexpensive commercially available fluoroalkyl anhydrides in concert with pyridine N-oxide are employed as the source of radicals. one-pot process involving trifluoroacetylation unprotected secondary benzyl amines followed by radical cyclization could also afford desired dibenz[b,e]azepines.

In contrast with the well-developed radical thiol-ene reaction to access anti-Markovnikov-type products, research on catalytic Markovnikov-selective hydrothiolation of alkenes is very restricted. Because catalyst poisoning metal catalysts by organosulfur compounds, limited examples transition-metal-catalyzed reactions have been reported. However, in this work, a directing-group-assisted styrenes thiols photoredox/cobalt catalysis found proceed smoothly afford Markovnikov-type sulfides...

Exohedral cuprofullerenes with 6-, 12-, or 24-nuclearity were obtained by utilizing fluorocarboxylic/dicarboxylic acid under solvothermal conditions. The 24-nuclear molecule presents a C60@Cu24 core–shell structure rhombicuboctahedron Cu24 coated on the C60 core, representing highest nuclearity in metallofullerene. resultant complexes show an efficient absorption of visible light as opposed to pristine C60. TD-DFT calculations revealed charge transfer from Cu(I) and O atoms fullerene moiety...
Abstract Long persistent luminescence (LPL) can store light energy in excited states and gradually release it as light. Organic host–guest systems provide a good platform for LPL, single‐color LPL is often achieved while multicolor challengeable.

Urban pumping stations often adopt the design of lateral-intake multiple forebays to accommodate pump units in a limited space and reduce interaction between operating units. However, full understanding undesired flows hydraulic characteristics remains limited, resulting flow-regulating measures relying on trial error. This study numerically investigated their implications, using Asia's largest urban water supply station as case study. The results show that flows, including flow...
