Coordination Chemistry of Boron Subphthalocyanine With BINOL Derivatives: Unexpected Oxidation to Oxa[4]Helicene and Properties of the Resulting Axially Coordinated Complexes Containing Oxa[4]Helicene and/or BINOL Derivatives

open access: yesChemistry – A European Journal, EarlyView.
Treatment of BINOL with a boron subphthalocyanine derivative resulted in the formation of a complex coordinated to an oxa[4]helicene derivative, which is generated via a ring‐closure reaction of BINOL. In contrast, treatment of the monomethyl ether of 1,1′‐bi‐2‐naphthol (BINOL) afforded the expected axially coordinated complex.

Tribenzotriquinacene Fused Dimers (“Fusodimers”)—Synthesis and Host–Guest Properties

open access: yesChemistry – A European Journal, EarlyView.
Two tribenzotriquinacene units merged with each other in either syn‐ or anti‐orientation of the bowls have become accessible in a short synthesis. In contrast to the anti‐isomer, the syn‐isomer forms 1:1 host–guest complexes with both C60 and C70 in solution and in the solid state, as shown by 1H NMR spectroscopy and x‐ray diffraction.

Exploring the Boundaries of Aromaticity in Complex Structures and Excited States Through Computational Analysis

open access: yesChemistry – A European Journal, EarlyView.
Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Anchoring MoS2 Petal‐Like Nanosheets on Coal‐Based Carbon Nanofibers by Surface Bonding Enable Li+/Na+ Batteries to Achieve Fast‐Charging Capabilities

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The unique structure connected by CS and COS interfacial bonds accelerates the reaction kinetics of lithium/sodium‐ion storage, while the addition of coal led to an increase in the mechanical strength of the carbon nanofibers, which improved the conductivity and stability of the materials.

Solvent‐Responsive Porous Organic Cage‐Based Membranes With Switchable Pore Openings for Molecular Sieving and Heavy Metal Recovery

open access: yesSmall, EarlyView.
An in situ fabricated porous organic cage membranes (PCM) exhibits reversible solvent pore switching property in response to water and methanol. Water stimulated structural rearrangement enables selective removal of Rh B and heavy metal ions (Ni2+ and Zn2+), whereas methanol stimulates the pore expansion promotes Ni2+ and Zn2+ ions recovery.

Identity Entanglement: Rethinking Marginality through the Intersectional, Liminal, and Antithetical

open access: yesSymbolic Interaction, EarlyView.
While identity research has given sustained attention to marginality, intersectionality, and the effects of power on identity, the formal interactional dynamics through which identities are constituted remain limited. I present identity entanglement as a useful framework for better understanding and articulating the relational complexities of identity.

SFK: Shape‐ and Function‐Grounded Keypoint Representation for Sequential Manipulation

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Sequential manipulation is the process by which robots perform multiple interdependent steps to accomplish composite tasks, demanding tight integration of perception, planning and execution. Existing methods incorporate explicit features such as category, semantics, 6D pose or affordance to enhance consistency, yet single‐feature ...
