ACS Macro Lett 2022 May 24:766-771. Epub 2022 May 24.

Department of Chemistry, Faculty of Engineering, Kanagawa University, 3-27-1 Rokkakubashi, Yokohama, Kanagawa 221-8686, Japan.

As a new example of intrinsically water-triggered phenomena, we report underwater dehydration of the statistical copolymers synthesized from triethanolamine borate (TEAB) methacrylate and styrene (St) induced by the hydrolysis of the pendant TEAB group. TEAB possesses high polarity owing to its internal Lewis adduct structure, which is lost by hydrolysis to triethanolamine (TEA) with a lower dipole moment. Therefore, the hydration of the copolymers became unfavorable through the hydrolysis of the pendant TEAB to TEA, despite polyol formation, and through a hydrophobic interaction based on St moieties becoming alternatively dominant.

π-d Electron-Coupled PBDIT/CdS Heterostructure Enables Hole Extraction for Efficient Photocatalytic Hydrogen Production.

ACS Appl Mater Interfaces 2022 May 27. Epub 2022 May 27.

Institute of New Carbon Materials, College of Materials Science and Engineering, Taiyuan University of Technology, Taiyuan 030024, China.

Construction of heterostructures is one of the most promising strategies for designing photocatalysts for highly efficient solar hydrogen (H) production because the introduction of an electron-donating counterpart contributes to more effective photon absorption, while the heterostructures benefit spatial carrier separation. However, the hole-transfer rate is usually 2-3 orders of magnitude slower than that of the electron-transfer rate within the heterostructures, ensuing serious charge recombination. Here, we find the energy band offset-driven charge-transfer behavior in a donor-acceptor (D-A)-conjugated polymer/CdS organic/inorganic heterostructure and realize hole-transfer improvement in cooperation with a further hole removal motif of poly(3,4-ethylenedioxythiophene) polystyrene sulfonate.
