Summary: The Clean Label (CL) trend, which emerged in the late 2000s, is a heuristic method used by consumers to make safe and healthy food choices. However, the definition of CL foods is vague and fails to effectively guide consumers' decisions.

Summary: A new ligand has been reported in this study which shows strong metal-ion dissociation barriers, higher oxidation reactivity, and relaxation rate response in a Mn-containing MRI contrast agent. There is a noticeable induction period before quinol oxidation and r(1) enhancement occurs, with ligand oxidation happening after most of the H2O2 has been depleted.

Summary: The heteroleptic multi-component double slider-on-deck system DS3 demonstrates a tight coupling of the motional speed of two distinct nano-circular sliders, despite a 2.2 nm separation. Synchronization of the motions in DS3 remains even when the faster slider is slowed down using small molecular brake pads. In contrast to the individual DS1 and DS2 systems, DS3 utilizes the motion of both sliders to drive two catalytic processes.

Summary: The self-assembly of supramolecular monolayers at liquid-solid interfaces is a well-established research field. In this study, a passivated Au(111) surface with a monolayer of iodine atoms was used to explore the effects of the underlying surface on interfacial monolayers. The experiments revealed that molecule-surface interactions can cause substrate-induced polymorphism and significantly affect the thermodynamic stability of supramolecular monolayers. This study highlights the crucial and specific thermodynamic influence of the underlying surface on monolayer formation.

Summary: Boolean operations with multiple catalysts as output are achieved using a two-component ensemble composed of a receptor and rotaxane. By activating the ensemble gate with the addition of metal ions and trifluoroacetic acid, a catalyst duo with dual catalytic output is generated, enabling a three-step reaction and producing dihydroisoquinoline as the output of a three-input logic AND gate operation.

Summary: We demonstrated the self-healing of a molecular machine's shuttling dynamics through negative feedback. Addition of zinc(II) to the copper(I)-loaded [2]rotaxane shuttle [Cu(R)](+) led to the replacement of copper(I) with static zinc(II)-loaded [2]rotaxane [Zn(R)](2+). Loss of dynamics was accompanied by fluorescence enhancement at lambda = 364 nm. However, the released copper(I) ions catalyzed the formation of a bis-triazole ligand, which selectively captured zinc(II), resulting in the restoration of copper(I) in the rotaxane and the regained dynamic shuttling motion of [Cu(R)](+). The healing process was conveniently monitored through diagnostic fluorescence changes.

Summary: This article describes a three-component molecular ensemble composed of a constitutionally dynamic cage 1, rotaxane 2, and luminophore 3, which functions as a signal transducer to assimilate and process three input signals, namely Zn2+, H+, and Cu+. It performs various logic operations (e.g., a 3-input NOR gate with catalytic output, 3-input AND gate with optical output) and operates as an unconventional 3-input demultiplexer.

Summary: When the basic ligand 3 was added to the heteroleptic three-component slider-on-deck [Ag-3(1)(2)](3+), it acted as a moderate brake pad (k(298) = 45 kHz). The resulting motion in the four-component slider-on-deck [Ag-3(1)(2)(3)](3+) allowed both ligand 3 and silver(i) to be continuously exposed and become catalytically active in a tandem Michael addition/hydroalkoxylation.

Summary: We demonstrate the locomotion capabilities of a biped on a tetrahedral track using chemical fuel, cooperative binding, and kinetic selectivity. The biped's movement is enabled by the binding of its dibenzyl amine feet to zinc porphyrin units and the subsequent protonation and binding to dibenzo 24-crown-8 sites, forming pseudorotaxane linkages.

Summary: A three-component network for OFF/ON catalysis was constructed, utilizing a protonated nanoswitch and a luminophore. The addition of silver(i) activated the network, leading to the proton-catalyzed formation of a biped structure and the assembly of a fast slider-on-deck (k(298) = 540 kHz).

Summary: This study synthesized two new core-annulated napthalene diimides (NDIs) which function as multidentate ligands, enhancing the stability of complexes formed with cations. These NDIs showed significant changes in their reduction potentials in the presence of Zn2+ ions and the reduction potentials could also be tuned with the presence of protons. Additionally, the dyes exhibited rare negative-halochromism in the presence of an acid, while maintaining a high emission quantum yield.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
