Advanced Sensor Research, Volume 4, Issue 7, July 2025.PQx‐Ph, a water‐soluble conjugated polyelectrolyte, enables rapid and selective fluorescence‐based detection of structurally distinct antibiotics via supramolecular assembly modulation. It achieves nanomolar sensitivity under mild conditions and preserves reliable sensing performance across NOM‐rich and biologically relevant water matrices, supporting ...

Molecular Interlayer for High‐Performance and Stable 2D Tin Halide Perovskite Transistor
Advanced Science, Volume 12, Issue 26, July 10, 2025.Molecular interlayers are designed for p‐channel 2D Sn halide thin‐film transistors, yielding exceptional performance metrics, a significant reduction in hysteresis, and enhanced ambient stability. The effectiveness of new molecular interlayers (TPOF1, TPOF2, and 2F‐TOPF2) is confirmed by surface treatment, demonstrating remarkable carrier mobility ...

Advanced Science, Volume 12, Issue 27, July 17, 2025.Dual biomimetic active sites, i.e., mononuclear {ZnII(L)(H2O)} and dinuclear {L2ZnII(CHO2)(OH)ZnIIL2}, have been successfully intergrated into a metal–organic cage, Zn20‐MOC. These two different active sites in Zn20‐MOC catalyze different steps of cascade trimerization of 1,2‐diaminocyclohexane. The mononuclear {ZnII(L)(H2O)} site catalyzes the initial

The Synthesis of Quinoxaline Derivatives
Nippon kagaku zassi, 1961 α-ケトグルタル酸ジエチルに ο-フェニレンジアミンを作用させて得られるβ-(3-オキシ-2-キノキサリル)プロピオン酸エチルを,オキシ塩化リンにより閉環して, 1-エトキシ-4-クロル-3a,9b-ジヒドロピロロ[1.2-a]キノキサリン(VII)を合成し,VIIから 1-エトキシ-3a,9b-ジヒドロピロロ[1.2-a]キノキサリンおよび6-エトキシ-3a,3b,6a,10b-テトラヒドロ-1,2,4-トリアゾロ[4.3-a]ピロロ[2.1-c]キノキサリンを得た。β-プロム-α-ケトグルタル酸ジエチルとο-フェニレンジアミンから,β-ブロム-β-(3-オキシ-2-キノキサリル)プロピオン酸エチルを経由して,trans-β-(2-キノキサリル)アクリル酸誘導体を合成した。
