In this work, we demonstrate the first synthesis of vinylene-linked 2D CPs, namely, poly(phenylenequinoxalinevinylene)s 2D-PPQV1 and 2D-PPQV2, via Horner-Wadsworth-Emmons (HWE) reaction C2 -symmetric 1,4-bis(diethylphosphonomethyl)benzene or 4,4'-bis(diethylphosphonomethyl)biphenyl with C3 2,3,8,9,14,15-hexa(4-formylphenyl)diquinoxalino[2,3-a:2',3'-c]phenazine as monomers. Density functional theory (DFT) simulations unveil crucial role initial reversible C-C single bond formation for...
Abstract Blue energy between seawater and river water is attracting increasing interest, as one of the sustainable renewable resources that can be harvested from water. Within reverse electrodialysis applied in blue conversion, novel membranes with nanoscale confinement function selective ion transport mediums are currently high demand for realizing higher power density. The primary challenge lies constructing well‐defined nanochannels allow low‐energy barrier transport. This work proposes a...
Titanium disulfide is a promising material for range of applications, including lithium-ion battery (LIB) anodes.
Abstract Although being attractive materials for photoelectrochemical hydrogen evolution reaction (PEC HER) under neutral or acidic conditions, conjugated polymers still show poor PEC HER performance in alkaline medium due to the lack of water dissociation sites. Herein, we demonstrate that tailoring polymer skeleton from poly(diethynylthieno[3,2‐b]thiophene) ( pDET ) poly(2,6‐diethynylbenzo[1,2‐b:4,5‐b′]dithiophene pBDT and poly(diethynyldithieno[3,2‐b:2′,3′‐d]thiophene) pDTT acetylenic...
The interest in two-dimensional conjugated polymers (2D CPs) has increased significantly recent years. In particular, vinylene-linked 2D CPs with fully in-plane sp

Abstract Large‐scale fabrication of self‐propelled micromotors is crucial to reach practical applications, but batch processes in manufacture make it challenging. Here, a novel ZnO yolk‐shell structure from large‐scale synthesis introduced as photocatalytic micromotor. The self‐asymmetry the enables them create asymmetric gradients, leading autonomous motion. Benefiting inner void space, possess higher incident light utilization and larger surface area for reactions. Moreover, when exposed...

Abstract Due to the drastic required thermodynamical requirements, a photoelectrode material that can function as both photocathode and photoanode remains elusive. In this work, we demonstrate for first time that, under simulated solar light without co‐catalysts, donor‐acceptor conjugated acetylenic polymers (CAPs) exhibit impressive oxygen evolution (OER) hydrogen (HER) photocurrents in alkaline neutral medium, respectively. particular, poly(2,4,6‐tris(4‐ethynylphenyl)‐1,3,5‐triazine) (...
Abstract Konjugierte Polymere sind attraktive Materialien für die photoelektrochemische Wasserstoffentwicklungsreaktion (PEC‐HER) unter neutralen oder sauren Bedingungen. Jedoch zeigen sie im alkalischen Medium immer noch eine geringe PEC‐HER‐Leistung aufgrund des Fehlens von Wasserdissoziations‐Zentren. Hier wir, dass durch Anpassung konjugierten acetylenischen Polymers (CAPs) Poly(diethinylthieno[3,2‐b]thiophen) ( pDET ) zu Poly(2,6‐diethinylbenzo[1,2‐b:4,5‐b′]dithiophen pBDT und...
