The Role of Ultra‐Thin Buffer Layers for Achieving Ultra‐Low Dark Currents in Single‐Component Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
Here, SubNc single‐component organic photodiodes (SC‐OPDs) are investigated, which achieve highly competitive performance metrics, including high EQE, ultra‐low JD, and high specific detectivity (D*). This study emphasizes the critical role of an organic buffer layer in studying the interface energetics and effects to achieve state‐of‐the‐art ...

Engineering Intelligent Graphene Oxide‐Cellulose Membranes: Suppressing Thermal Runaway for a Safer Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A novel thermos‐responsive hydroxypropyl cellulose/graphene oxide (HPC/GO) composite membrane is fabricated for reversible temperature‐gated ion transport in aqueous zinc‐ion batteries. Enabled by LCST‐driven structural transition, unimpeded ion diffusion at room temperature delivers high capacity, while elevated temperature suppresses transport; full ...

Syntheses of Bis-Epoxy Compounds from Exo and Endo-Norbornene carboxylic Esters and Polymerization of the Epoxy Compounds

open access: yesThe Journal of the Society of Chemical Industry, Japan, 1966
エキソおよびエンドノルボルネンカルボン酸と2 官能性フェノール類とのエステル化反応で2 種類のビスエステル, すなわちエキソ,エキソ異性体とエンド,エンド異性体を合成した。またヒドロキノンエステルではエキソ,エンド異性体も単離された。さらにそれらをエポキシ化してビスエホキシ化合物を得た。これらのエポキシドのトリエチルアルミを触媒とする重合反応では重合性は低く両異性体間には著しい差異は認められなかった。また酸無水物との反応についても若干検討した。
