Visible-Light-Driven Reductive Carboarylation of Styrenes with CO2 and Aryl Halides.

open access: yesJournal of the American Chemical Society, 2019
The first example of visible-light-driven reductive carboarylation of styrenes with CO2 and aryl halides in a regioselective manner has been achieved. A broad range of aryl iodides and bromides were compatible with this reaction.

Rational Fine‐Tuning of MOF Pore Metrics: Enhanced SO2 Capture and Sensing with Optimal Multi‐Site Interactions

open access: yesAdvanced Functional Materials, EarlyView.
A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.

How to Recognize Clustering of Luminescent Defects in Single-Wall Carbon Nanotubes [PDF]

open access: yesNanoscale Horizons, 2024, 9, 2286 - 2294
Semiconducting single-wall carbon nanotubes (SWCNTs) are a promising material platform for near-infrared in-vivo imaging, optical sensing, and single-photon emission at telecommunication wavelengths. The functionalization of SWCNTs with luminescent defects can lead to significantly enhanced photoluminescence (PL) properties due to efficient trapping of

Polarization‐Driven Molecular Alignment of Azopolymer for Dual‐Encrypted and Moiré Animation‐Based Anti‐Counterfeiting

open access: yesAdvanced Functional Materials, EarlyView.
A multi‐layered anti‐counterfeiting platform is developed based on an azopolymer (PAzo) system. By leveraging the molecular orientation control of PAzo under linearly polarized light (LPL), encrypted patterns are fabricated that remain invisible under standard conditions and require polarized optical microscopy (POM) for decryption.

Flexibility and Dynamicity Enhances and Controls Supramolecular Self‐Assembly of Zinc(II) Metallogels

open access: yesAdvanced Functional Materials, EarlyView.
Zinc(II) coordination complexes with tunable aryloxy‐imine ligands exhibit controllable supramolecular self‐assembly into hierarchical fibrous structures. Coordination‐driven stacking, not π–π interactions, enables gelation, dynamic assembly/disassembly, and enhanced nanomechanical properties.
