Exploring high-activity and low-cost electrocatalysts for the hydrogen evolution reaction is key to developing new energy sources, but it faces major challenges.
The recent advances in visible-light photocatalytic deuteration of X–H, C–halogen, CC, and other bonds for the synthesis deuterium-labeled organic molecules have been summarized according to type bond deuterated reactions.
Abstract A protocol for trans -hydroboration of indole derivatives using heterogeneous photocatalysis with NHC-borane has been developed, addressing a persistent challenge in organic synthesis. The protocol, leveraging high crystalline vacancy-engineered polymeric carbon nitride as catalyst, enables diastereoselective synthesis, expanding substrate scope and complementing existing methods. approach emphasizes eco-friendliness, cost-effectiveness, scalability, making it suitable industrial...
Value-added chemicals, γ-aryl ketones and naphthalenes, were conveniently synthesized from readily available toluenes enones through the synergistic combination of photoredox Lewis acid catalysis. The direct synthesis represents a rare example Giese reactions between benzylic C(sp3)–H that avoids use prefunctionalized metallic nucleophiles. Naphthalene derivatives accessed one-pot reaction/Friedel–Crafts hydroxyalkylation/oxidative aromatization sequential transformation.
Fullerene molecules have attracted considerable interest because of the unique curved aromatic π-conjugated systems. However, complicated and costly technologies for purification highly pure fullerenes hamper easy access to these attractive consequently limit most fullerene applications. Here, we report discovery a carcerand-like cage acting as stand-alone host efficient separation C60 C70 from soot. The cage, built through self-assembly metal coordination, is capable quantitatively...
The visible-light-mediated energy transfer catalysis plays a pivotal role in the photochemical synthesis. Although many significant advances this field have been achieved within past decade, knowledge of photochemically tunable metal–ligand interaction for photocatalysts, manipulation principle excited-state properties, and available electronic excitation free bound substrates, which makes it possible to design some photo- auxiliary catalysts based on proposed mechanism, is still sparse. In...
Reported herein is an unprecedented copper-catalyzed site-selective δ-C(sp3)–H bonds activation of aliphatic sulfonamides for constructing the synthetically useful seven-membered N-heterocycles. A key to success use in-situ-formed amide radicals, activate inert C(sp3)–H bond, and inexpensive TMSNCO, as a coupling reagent under mild conditions. To best our knowledge, this represents first alkylamine derivatives five-membered synthon prepare
A visible-light photocatalytic hydrogen evolution cross-coupling of silanes with H 2 O, alcohols, phenols, and silanols via synergistic combination photoredox polarity reversal catalysis has been developed.
Two triptycene rotators have been covalently linked to the backbone of a quinquepyridine (QPY) foldamer at second and fourth pyridine rings, respectively, form molecular spur gears. The studies revealed that QPY as stator can reversibly control intermeshed demeshed states gears due linear-to-helical conformational switching triggered by complexation/decomplexation.
We report here the first corannulene-based molecular cage, constructed via metal-induced self-assembly of ligands. In sharp contrast to those assembled planar π-conjugated analogues corannulene, at ambient and elevated temperatures, cage exists as an ensemble four stereoisomers (two pairs enantiomers), all which possess a D5-symmetric (regardless counteranions) inherently helical structure. Decreasing temperature shifts equilibrium between different enantiomers. At low temperature, only one...
In artificial molecular devices, flexible, linear chains typically exhibit very weak capability in inhibiting motion. Herein, we describe the dynamic properties of a series turnstiles consisting rigid frame and phenyl rotator flanked with alkoxymethyl substituents. The long, flexible substituents act as elastic baffles to inhibit rotations at medium fast speeds on NMR time scale. When moves slowly, become more relaxed, thus obtaining an opportunity completely thread through cavity...
A series of N2,N6-bis(triptycene-9-yl)pyridine-2,6-dicarboxamides 1–4 were designed and synthesized. Due to rotational constraint the 2,6-diamidopyridine bridge, triptycene components in systems are held together. X-ray structures show that molecules adopt a gear-like geometry solid states. DFT (B3LYP/6-31G(d)) calculations predict C2 conformation as global minimum for 1 2 suggest that, through slippage transition process, rotation one component would give rise rocking vibration counter due...
Abstract The improvement of time resolution in time-of-flight positron emission tomography (TOF-PET) relies on the development scintillation materials and photodetectors. With introduction Cherenkov TOF-PET, higher requirements have been placed intrinsic timing performance Our team has proposed a Radiator Window Photomultiplier tube (CRW-FPMT) that uses radiator directly as light window, which eliminates boundary between scintillator photodetector for fast resolution. This paper mainly...
Abstract Systematic construction of isoreticular hydrogen‐bonded organic frameworks (HOFs) promises tailored material properties crucial for diverse applications, yet is challenging due to the weak, flexible, and non‐directional nature hydrogen bonds. Herein, we develop an “integrated monomer synthesis‐framework assembly” ( ISA ) methodology constructing a series HOFs. Unlike traditional methods where monomers are first synthesized then assembled into HOFs, system employs dicyandiamide rigid...
