非富勒烯受体（NFA）平台：涵盖当前主流明星分子 Y6（CAS: 2304444-49-1）、N3（即PC61BM的同系物，CAS: 2640657-07-2）、BTP-eC9（CAS: 2598965-39-8）、PY-IT、D18/D18-Cl（CAS: 2433725-54-1 / 2433725-53-0）及 L8-BO（CAS: 2668341-40-8）等。其中，D18 与 L8-BO 的组合表现尤为突出——在相同标准器件结构下，实现了 20.24% 的PCE，Voc达 0.92 V，Jsc为 26.42 mA/cm²，FF高达 83.26%，代表了目前溶液处理型OPV的效率巅峰。值得一提的是，作为该产品线中的经典代表，富勒烯C60衍生物 PC61BM 依然发挥着不可替代的作用。作为一种公认的基准材料，PC61BM不仅在有机太阳能电池（OSC）中广泛应用，更在钙钛矿太阳能电池（PSC）领域扮演着关键角色——它既是高效的电子传输层（ETL），也是优异的晶界钝化剂。为满足高校、研发机构及商业制造商的差异化需求，ChemWhat已将该产品标准化为两个纯度等级：99.5%用于常规研究，99.9%则专为高精度器件制备而设。ChemWhat不仅实现上述NFA产品的稳定供应，更通过优化合成路线，将关键中间体纳入标准品目录，助力客户自主开发新型受体结构。 https://www.youtube.com/watch?v=ZPw-35OKxb4

As the world races toward net-zero, organic photovoltaics—or OPV—are stepping into the spotlight. Lightweight, flexible, semi-transparent, and printable, OPV is no longer just a lab curiosity—it’s powering the future of wearable tech, smart windows, and indoor energy harvesting. At the heart of this revolution is ChemWhat, a premium materials brand from Watson International, delivering the high-purity, structurally precise molecules that turn scientific breakthroughs into real-world devices. ChemWhat’s strength lies in its complete OPV ecosystem—from donors and acceptors to critical intermediates. Its polymer donors like PM6 and PTQ10, paired with next-gen non-fullerene acceptors such as L8-BO and PY-IT, are setting new efficiency records. In standard device architectures, PM6:L8-BO achieves an impressive 18.78% power conversion efficiency, while D18:L8-BO soars to 20.24%—among the highest ever reported for solution-processed solar cells. And PTQ10:PY-IT delivers exceptional current ou...

A standout component of this lineup is the Fullerene C60 derivative, PC61BM. Widely recognized as a benchmark material, PC61BM plays a pivotal role not only in Organic Solar Cells (OSCs) but also in Perovskite Solar Cells (PSCs), where it functions as a highly efficient Electron Transport Layer (ETL) and grain boundary passivator. To address the varied requirements of universities, R&D centers, and commercial manufacturers, ChemWhat has standardized this product into two distinct purity levels: 99.5% for general research and 99.9% for high-precision device fabrication. https://www.youtube.com/watch?v=IAPYD3RoUQI

Although Sulfo-TAG NHS-Ester is not a new molecular structure, achieving high purity and batch-to-batch consistency on an industrial scale presents considerable technical challenges. ChemWhat’s UK-based research and production facilities operate under a globally standardized quality control system, ensuring every batch meets the highest international standards of purity, reactivity, and stability. • High-Purity Synthesis Control: Optimized synthesis pathways and HPLC verification ensure purity ≥95%. • Batch Consistency and Stability Validation: Strict control of reaction parameters and lyophilization processes maintains consistent performance across production cycles. • Compliance with Global Regulations: Manufacturing adheres to ISO and EU chemical management standards (including REACH), ensuring suitability for worldwide use in life science applications. Through this systematic approach, ChemWhat has successfully transformed Sulfo-TAG NHS-Ester from a laboratory-scale reagent into a ...
