The synthesis of novel photostable fluorescein-based dyes containing an s-triazine UV absorber and a HALS unit and their acrylonitrile copolymers

Synthesis of 14-Aryl- and Alkyl-14H-dibenzo[a,j]xanthenes Catalyzed by Silica-supported Ferric Hydrogensulfate

“…[1][2][3] They are used as dyes 4 in laser technologies, 5 in fluorescent materials for visualization of biomolecules, 6 as intracellular pH indicators, 7 as photostable dyes, polymerizable light emitting dyes, 8,9 and white organic light emitting dyes. 10 Natural xanthene dyes may also be extracted from soil and plants such as Indigofera longeracemosa.…”

Effect of Alkyl Substitution on the Electronic Structure and Spectrum of Rhodamine

“…遗传学、 环境化学、单 个 分子检测、 信息科学、 荧光标 记、激光染料等方面 [1][2][3][4][5] . 虽然前人已对其性能与结 构的关系进行了较多的实验研究 [6][7][8][9] , 并合成不同取 代基的罗丹明类化合物 [10][11][12][13][14] , 但缺乏较系统的理论 解释. 为了更高效地开发新型高性能罗丹明类化合 物, 迫切需要有效的理论指导.…”

Synthesis of Spirooxindoles through Cyclocondensation of Isatin and Cyclic 1,3‐Diones

“…Xanthene derivatives are present as structural building blocks in various natural products exhibiting analgesic, antibacterial , antiviral , anti‐inflammatory , and anti‐proliferative activities. The xanthene derivatives are also being utilized as antagonists for paralyzing action of zoxazolamine and in photodynamic therapy and photostable dyes and polymerizable light‐emitting dyes , in addition to their uses as fluorescent dyes and pH‐sensitive fluorescent materials for visualization of biomolecules , along with their use in laser technologies . Many xanthene derivatives are also potent nonpeptidic inhibitors of recombinant human calpain I and novel CCRl receptor antagonists (Fig.…”
