Summary: The synthesis of helical crystals from achiral molecules is crucial due to their unique applications in various fields depending on chirality. Surprisingly, many examples of helical crystals of achiral molecules have been obtained without specific synthetic strategies. This study proposes the application of Eshelby twist to noncovalent molecular crystals by introducing screw dislocations, and successfully synthesizes helical tube crystals of achiral titanyl phthalocyanine through vapor-phase crystal growth. The presence of screw dislocation induces crystal twisting along the growth direction to release strain.

Summary: In this study, the relationship between the helical pitch of the helical nanofilament phase formed by the bent-core molecule NOBOW and the concentration of achiral dopants 5CB and octane was investigated using linearly polarized resonant soft X-ray scattering (RSoXS). The results showed that the variation of the helical pitch is related to the concentration of 5CB and is not temperature-dependent. Doping rodlike immiscible 5CB led to a shortening of the helical pitch, which was attributed to a change in interfacial tension. This study provides insights into the phase behavior of binary systems and enables control over the pitch length.

Summary: This study introduces a novel self-assembled system where molecular chirality can be transferred and stored in a helical superstructure, with the ability for self-recovery after being temporarily destroyed. Through a cross-linking strategy, the induced helical superstructure can achieve permanent memory. The unprecedented chiral switching in the absence of a chiral source opens up new possibilities for the design and application of chiral materials.

Summary: In this study, we successfully developed an entropically favored helical supramolecular self-assembly system using a triphenylamine-based derivative 4 in a green solvent. The transformation from helical structure to random structure and then to achiral nanorods was studied by varying the concentration of achiral stimuli (Fe2+ ions). In addition, the metal-free helical supramolecular self-assembly showed enantioselectivity in differentiating between L- and D-prohne, achieved through chiral stimuli-induced structural modulation.

Summary: Lead halide perovskites and their derivatives exhibit unique semiconductor properties and have various applications in fields such as photovoltaics, solid-state lighting, and photocatalysis. Recent research has shown that incorporating chiral organic cations can result in chiral metal-halide semiconductors with intriguing properties, such as chiroptical activity and chirality-induced spin selectivity. However, understanding the structural origin of this chiroptical activity remains challenging.

Summary: This study introduces an innovative method to impart helical chirality to covalent organic frameworks (COFs) and fabricate a family of chiral COF nanotubes. The helical polymer nanotubes are effectively converted into COF nanotubes with impressive surface areas while preserving their helical morphology and chiroptical properties. These COFs can be further transformed into more stable and functional COF nanotubes through monomer exchange, preserving the mesoscopic helical chirality. This research highlights the potential of mesoscopic helicity in conferring COFs with favorable chiral properties and provides novel insights into the development of multifunctional COFs in the field of chiral materials chemistry.

Summary: Encapsulation of achiral dyes into hollow cages can inhibit aggregation-caused quenching behavior and promote the induction and amplification of CPL, leading to the synthesis of two chiral hexahedral cages with crown ether or methoxymethyl moieties. The host-guest complexes exhibit strong CPL emissions in solution, with an order of magnitude amplification of g(lum) values upon crystallization.

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.
