High Free‐Volume Imidazole‐Based Ionomers for High‐Temperature Proton Exchange Membrane Fuel Cells

Advanced Science, EarlyView.
High free‐volume imidazole‐based ionomers (PF4IM‐72) enable enhanced phosphoric acid uptake and efficient proton transport, delivering peak power densities of 0.645 W cm−2 at 160 °C and 0.838 W cm−2 at 200 °C in HT‐PEMFCs. This work highlights a promising platform for next‐generation ionomers with improved high‐temperature performance and stability ...

Synthesis of Tetrachloro-Bisphenol A by Chlorination of Bisphenol A

The Journal of the Society of Chemical Industry, Japan, 1971
一般液相塩素化触媒を用い, 酢酸溶媒中で BPA の塩素化を行ない, 塩化アルミニウム触媒が最も適当な触媒と認めた。反応条件は BPA 仕込み濃度 10%, 触媒濃度 1% 以上, 反応温度 30～33℃ が適切であった。触媒の選択作用は強く, 無触媒とは異なった選択逐次反応で進行する。Cl2流速/BPA (l/min・mol) 0,25～0.60 の各実験における BPA の消失速度から擬一次反応の成立が確認され, その速度定数たと反応時間tの積τ と BPA,反応中間物の濃度の関係はほぼ同一曲線上にプロットされた。その曲線から, 試行錯誤により求められた各中間物の相対速度定数Kは, K2=k2/k1=1.3, K2=k3/k1=1.2, K4=k4/k1=1.8, K5=k5/k1=≒0 ...

Interfacial Proton‐Relay Microenvironment Enables Self‐Driven Singlet Oxygen Generation under Neutral Conditions

Advanced Science, EarlyView.
An interfacial proton‐relay microenvironment at MoS2‐CuCl heterostructures enables selective O2 activation to 1O2 under neutral conditions. Electron‐deficient sulfur sites mediate proton transfer to Cu‐bound O2, accelerating *OOH hydrogenation while suppressing O─O bond cleavage, achieving stable, efficient pollutant removal.

Tunable Synthesis of Multi‐Responsive NH‐Containing Helical Nanographenes With a Chiroptical Switching Function

Angewandte Chemie, EarlyView.
The Scholl reaction of 1,3,6,8‐tetrakis(oligophenyl)‐appended carbazoles afforded stable NH‐containing helical nanographenes, which showed significant redshift and reversible on/off switching of CPL upon the addition of base and acid, respectively. Furthermore, excited‐state proton transfer occurred in dimethyl sulfoxide to generate anionic species ...

Selective Sequential Depolymerization of Mixed Plastics Mediated by Photothermal Conversion

Angewandte Chemie, EarlyView.
This work provides a selective sequential depolymerization strategy for mixed plastic waste. The method enables depolymerization of poly(L‐lactide), polystyrene, and poly(ethylene terephthalate), including their post‐consumer plastics. Without presorting, monomer separation is achieved by leveraging the distinct chemical reactivities of each polymer in
