K isotopes reveal fluid exsolution and Li enrichment in the Koktokay No. 3 pegmatite dike

Shan-Ke Liu, Ben‐Xun Su, Weiwei Li, Dong-Mei Tang et autres

Introduction: Lithium–cesium–tantalum pegmatites are critical sources of rare metals, yet the mechanisms of their formation, especially the role of fluids in elemental and isotopic fractionation, remain debated. Materials and methods: We investigated the Koktokay No. 3 pegmatite dike, the largest rare-element pegmatite …

Aggregation-Free, Highly Soluble CN-Terminated Dicyclopentadiene-Fused Rylenes

Liuying Jiao, Ya Zou, Wei Fan, Yi Han et autres

Rylenes, known for their excellent photochemical properties, hold great promise in OLEDs, solar cells, and bioimaging applications. However, the solution-phase synthesis of long rylene molecules is often hindered by poor solubility and low stability. In this work, we present an efficient synthetic …

Peri -pentacene and Peri -hexacene Diradicaloids

Ya Zou, Liuying Jiao, Yi Han, Longbin Ren et autres

Peri -acenes are valuable models for zigzag-edged graphene nanoribbons, but their synthesis poses significant challenges. In this study, stable derivatives of peri -pentacene ( Peri-P ) and peri -hexacene ( Peri-H ) were synthesized. Through kinetic blocking and a synergistic captodative effect, …
