Rainbow Photonic Crystals: Self‐Assembly of Carbohydrate Bottlebrushes Block Copolymers

open access: yesAdvanced Materials, EarlyView.
Full‐color reflective 1D photonic crystals, capable of a tunable, responsive, and reversible color with high repeatability, are created from the self‐assembly of carbohydrate‐based brush block copolymers (BR01‐04). Abstract Tunable and responsive photonic crystal systems are the subject of great research interest owing to their ability to actively ...

High Charge Carrier Mobility in Non‐Conjugated 3D Covalent Organic Frameworks

open access: yesAdvanced Materials, EarlyView.
A non‐conjugated 3D COF constructed via boronate ester linkages from tetraphenylene and pyrene‐based monomers is reported, which exhibits a high charge carrier mobility of 14 ± 1 cm2 V−1 s−1. ABSTRACT π‐Conjugation, π–π stacking, and long‐range order play a central role in determining charge transport efficiency in organic materials.

Hydrogelation via Supramolecular Copolymerization of Structural Water within Adaptive Metal–Organic Fibers

open access: yesAdvanced Materials, EarlyView.
Structural water is harnessed as an active co‐monomer to drive supramolecular polymerization in bulk water. Zinc(II) Salphen complexes confine water molecules to form hollow, metal–organic nanofibers that assemble into adaptive hydrogels with thermoresponsive mechanics and selective chiral recognition.
