Local Electron Donor Defects Induce Dipole Polarization Boosting on Covalent Organic Frameworks to Promote Photocatalysis

ACS Materials Letters, Journal Year: 2023, Volume and Issue: 5(11), P. 2877 - 2886

Published: Sept. 27, 2023

Covalent organic frameworks (COFs) have been remarkably evolved within the field of photocatalysis owing to their customizability and targeted functionalization. However, exciton effect arising from Coulomb interaction among electrons–holes cannot be disregarded. Exploring new approaches regulate dissociation on COFs facilitate is significant. Within this work, localized defects were fabricated skeleton by one-step synthesis method introducing monoaldehyde electron donors (pyrene, ferrocene, triphenylamine). The formation D–A configuration can directionally change local electronic structure charge distribution induce enhanced dipole polarization, thus, promoting enhancing photocatalytic activity. Among them, pyrene donor-constructed defective COF exhibited a 7.8-fold increase in aqueous-phase oxygen-containing photopolymerization rate relative pristine COF, with conversion 80% 30 min.

Dynamic‐bond‐mediated Chain Reptation Enhances Energy Dissipation of Elastomers

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(19)

Published: March 12, 2024

Abstract Vibrations with various frequencies in daily life and industry can cause health hazards fatigue failure of critical structures, which requires the development elastomers high energy dissipation at desired frequencies. Current strategies relying on tuning characteristic relaxation time polymer chains are mostly qualitative empirical methods, it is difficult to precisely control damping performances. Here, we report a general strategy for constructing dynamic crosslinked fluid gels that provide controllable ultrahigh dissipation. This realized by dynamic‐bond‐mediated chain reptation fluids network, where dominated presence well‐defined dissociation bonds almost independent their molar mass. Using prototypical supramolecular polydimethylsiloxane elastomers, demonstrate exhibit performance (10 −2 ~10 2 Hz), exceeding typical state‐of‐the‐art silicone materials. Their shock absorption over 300 % higher than commercial rubber under same impact force.

Tribochemically Controlled Atom Transfer Radical Polymerization Enabled by Contact Electrification

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(37)

Published: July 29, 2023

Traditional mechanochemically controlled reversible-deactivation radical polymerization (RDRP) utilizes ultrasound or ball milling to regenerate activators, which induce side reactions because of the high-energy and high-frequency stimuli. Here, we propose a facile approach for tribochemically atom transfer (tribo-ATRP) that relies on contact-electro-catalysis (CEC) between titanium oxide (TiO2 ) particles CuBr2 /tris(2-pyridylmethylamine (TPMA), without any input. Under friction induced by stirring, TiO2 are electrified, continuously reducing /TPMA into CuBr/TPMA, thereby conversing alkyl halides active radicals start ATRP. In addition, effect reaction was elucidated theoretical simulation. The results indicated increasing frequency could reduce energy barrier electron from /TPMA. this study, design tribo-ATRP successfully achieved, enabling CEC (ca. 10 Hz) access variety polymers with predetermined molecular weights, low dispersity, high chain-end fidelity.
