Reusable Polyphenol Building Blocks Enable Recyclable Epoxy‐Amine Thermosets via Methanolysis
Angewandte Chemie, EarlyView.A biobased epoxy–amine platform was developed using functional building blocks derived from polyphenols. These thermosets exhibited tunable mechanical and thermal properties, together with efficient, catalyst‐free chemical recycling via methanolysis. Beyond the recovery of reusable building blocks, the recycled polyols could be further upcycled into ...

Advanced Science, EarlyView.In this study, an efficient screening system is developed for plant metabolites to find a compound, 7‐epi‐10‐deacetyltaxol, inhibits tissue elongation. It suppresses plant growth through brassinosteroid and microtubule pathways. It is later applied to animal cells and human tumor organoids, resulting in similar cell division suppression. These findings

Closed‐Loop Recyclable Solid Polymer Electrolytes via Dynamic Lipoate Cross‐Linking
Angewandte Chemie, EarlyView.A visible‐light‐driven, closed‐loop recyclable solid polymer electrolyte is built from a bio‐derived lipoate cross‐linker, poly(ethylene glycol) bis(lipoate) (PEG‐LP2), synthesized from α‐lipoic acid. Dynamic disulfide exchange enables efficient DBU‐catalyzed depolymerization and photo‐repolymerization, regenerating membranes that retain high ionic ...

A Tert‐Alkyl Terephthalate Derivative as a Universal Degradable Unit for Condensation Polymers
Angewandte Chemie, EarlyView.A sterically bulky dicarboxylic acid core bearing a tertiary alkyl ester enables photocatalytic C─O bond cleavage via generation of a stabilized tertiary alkyl radical. Incorporated into polyarylate, polyurethane, and polyester, this universal trigger facilitates efficient degradation under identical conditions (up to 99% within 2–4 h). Remarkably, the

On the Depolymerization of Polycapramide
Kobunshi Kagaku, 1961 アルカリ系触媒によるポリカプラミドの解重合について検討した。反応は約250℃ ですみやかに行なわれるが同時に多くの塩基性不純物を副生しその精製に手数がいるので工業的には問題がある。低温度の解重合においては反応系の減圧度がラクタムの留出速度に影響する。重合, 解重合反応速度と系内におけるe-カプロラクタムの溶解量に関係がある。N-アルカリ金属化したアミドはアニオンを媒介として他のアミドと容易にアミド交換反応を行ない重合, 解重合反応が行なわれる。
