Bolapolyphiles With Bulky Carbosilane‐Based Lateral Groups—Reticular Design of Liquid Crystalline Pentagonal Honeycombs

open access: yesChemistry – A European Journal, EarlyView.
T‐shaped bolapolyphiles with highly branched carbosilane‐based side‐groups self‐assemble into liquid crystalline honeycombs composed of type‐2 pentagonal prismatic cells and p2gg plane group symmetry. ABSTRACT Periodic pentagon tessellations are rarely observed in self‐assembled molecular systems.

Synthesis of Chiral‐at‐Sulfur(VI) Sulfonimidamide Brønsted Acids

open access: yesChemistry – A European Journal, EarlyView.
A simple, modular route to chiral‐at‐sulfur(VI) Brønsted acids is described, delivering S‐chiral sulfonimidamides, C2‐symmetric acids, and BINOL‐based hybrid systems through stereospecific reactions of sulfonimidoyl fluorides and chlorides. ABSTRACT Herein, we report an efficient and simple strategy to access diverse chiral‐at‐sulfur(VI) Brønsted acids.

Chiral Cycloparaarylenes Incorporating Binaphthyl Units: Dramatic Effects of Peripheral Functionalization on (Chir)Optical Properties

open access: yesChemistry – A European Journal, EarlyView.
Chiral cycloparaarylenes (CPAs) incorporating binaphthyl units were synthesized. The methoxy‐substituted and methylenedioxy‐bridged systems adopt D3‐ and C3/C1‐symmetric structures, respectively. They exhibited distinct solid‐state emission and aggregation‐induced emission enhancement (AIEE).

Synergistic Molecular Engineering and Crosslinking Topology for High‐Temperature Energy Storage in All‐Organic Dielectrics

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A synergistic strategy combining CF3 group incorporation and crosslinking topology is employed to tailor chain spacing and local ordering in all‐organic dielectrics. This design effectively suppresses carrier migration and enhances polarization, yielding outstanding high‐temperature energy storage performance (e.g., 8.95 J cm−3 with 90% efficiency at ...
