Novel Fluorescence Probe for Fe³⁺and Application of Imaging in Living Cells

A Novel Rhodamine B Fluorescent Probe for Hg2+: Synthesis and Evaluation

“…A novel fluorescent probe R based on rhodamine B was synthesized by the condensation of rhodamine B hydrazide and phenylglyoxal monohydrate, followed by reduction with NaBH 4 , and its structure was characterized by 1 H NMR, 13 的方法主要有高效液相色谱法(HPLC) [4] 、原子发射光谱 法(AES) [5] 、原子吸收光谱法(AAS) [6] 、电感耦合等离子 体质谱法(ICPMS) [7] [23,24] . 因此, 本文在罗丹明 B 结构中引入羟乙基肼基…”

A Series of Red Dyes: Synthesis, Optical Properties and Application in Protein Labeling

“…首先 以 3-N,N-二乙基氨基酚为原料以 3 步反应且较高收率得 到系列新型红色荧光染料 HQ1～HQ4, 发射波长均大 于 600 nm. 用 1 H NMR, 13 C NMR, IR, HRMS 对结构进 行了表征, 检测了新型染料的光学性质, 斯托克斯位移 增加到 70 nm 以上, 具有良好的光稳定性和水溶性. 对 牛血清白蛋白(BSA)进行标记纯化后测得这些染料的标 记蛋白的染 料/蛋白质(D/P)值高达 1.5～1.9.…”
